American consulate general: how it works, services offered and visa processing

An American consulate general is a regional diplomatic post led by a consul general in a large non-capital city. It provides passport, birth registration and emergency services to US citizens. It also issues nonimmigrant and immigrant visas to foreign nationals. According to the National Museum of American Diplomacy (October 2022), the United States maintains only one embassy and ambassador in a foreign country's capital, while consulates carry out the same core services on a smaller regional scale under the ambassador's lead. If you live outside the United States and have an approved immigrant petition, a US Department of State consulate is also where you complete the 8-step consular processing path for a Green Card.

What is an American consulate general?

When you book a US visa interview or need a US passport abroad, you will visit either a US embassy or an American consulate. In diplomatic terms, all embassies, consulates and other diplomatic posts in foreign countries are collectively known as missions.

The United States has only one embassy and one ambassador in the capital city of a foreign country. In large countries, the United States operates several consulates in addition to the capital embassy, placing them in other large cities across the host nation.

A consul general leads the consulate. To make sure the United States has a unified approach to its foreign policy goals across the entire country, consulates follow the lead of the ambassador in the host country. While the embassy devises national policies, diplomats at a regional consulate often carry out more of the work on the ground and may take the lead on specific regional foreign policy goals.

Inside a US mission, work is divided across specialized teams. When a US ambassador convenes a Country Team meeting, the heads of the Consular, Political, Economic, Management, Security and Public Diplomacy sections gather to coordinate operations. For visa applicants and traveling Americans, the Consular section is the public face of the mission.

US embassy vs. American consulate general: how they compare

For most applicants and US citizens living abroad, the day-to-day experience at a consulate general looks very similar to the consular section of an embassy. Both operate under the Department of State's Bureau of Consular Affairs, which is led by the Assistant Secretary for Consular Affairs under the Under Secretary for Management.

The table below compares a US embassy and a US consulate based on guidance from the National Museum of American Diplomacy and USCIS.

What services does an American consulate general provide?

The Bureau of Consular Affairs states that its highest priority is to protect the lives and serve the interests of American citizens abroad. At the same time, consular teams issue millions of US passports each year and screen foreign nationals applying for visas to enter the United States.

Services at a consulate fall into three main areas: American citizen services, visa services for foreign citizens, and interagency cooperation.

• Routine citizen documentation: Consulates issue US passports and handle birth registrations for visiting or resident American citizens in the host country.
• Citizen crisis and life-event support: Across the globe, consular staff assist US citizens during births, adoptions, medical emergencies, deaths, arrests and disasters.
• Nonimmigrant visas: Consular officers adjudicate and issue visas for foreign citizens who want to visit, study or work temporarily in the United States.
• Immigrant visas: Consulates abroad process immigrant visa applications through consular processing so eligible beneficiaries can travel to the US and be admitted as lawful permanent residents.
• Interagency cooperation: Consular posts collaborate with US and foreign law enforcement agencies to combat international crime, verify records and track human rights abuses.

How consular processing works for a Green Card (8 steps)

If you are applying for lawful permanent resident status (a Green Card), your location determines which government pathway you use. According to USCIS (updated July 20, 2023), if you are already inside the United States, you can apply without returning to your home country through adjustment of status. If you are outside the United States, or live in the US but choose to apply abroad, you apply for an immigrant visa at a US Department of State consulate abroad. This pathway is called consular processing.

Before submitting a petition, USCIS advises checking with the consulate and the Department of State website. Once you are the beneficiary of an approved immigrant petition and an immigrant visa number is immediately available, your case moves through eight steps defined by USCIS.

• Step 1: Determine your basis to immigrate. Confirm which Green Card eligibility category fits your situation, such as a family relationship, employment, investment, refugee or asylum status, or special provisions.
• Step 2: File the immigrant petition. For family-based cases, a US citizen or lawful permanent resident relative files Form I-130 (Petition for Alien Relative). For employment-based cases, a US employer files Form I-140 (Petition for Alien Worker), or an investor files Form I-526 (Immigrant Petition by Alien Entrepreneur) for themselves. In special categories, you or someone else may file Form I-360 (Petition for Amerasian, Widow(er), and Special Immigrant). Most humanitarian programs do not require an immigrant petition, though additional requirements apply.
• Step 3: Wait for a decision on your petition. USCIS notifies the petitioner when it makes a decision. If denied, the notice states the reasons and whether you may appeal. If approved and you are processing abroad, USCIS sends the approved petition to the Department of State's National Visa Center (NVC), where it stays until an immigrant visa number is available.
• Step 4: Wait for notification from the National Visa Center. The NVC collects visa application fees and supporting documentation. It notifies both the petitioner and the beneficiary when it receives the petition, when a visa number is about to become available, and when to submit immigrant visa processing fees (called fee bills) and supporting documents.
• Step 5: Go to your consular appointment. Once a visa is available or your priority date is current (earlier than the cut-off date listed in the monthly Visa Bulletin), the consular office schedules your interview, processes your case and decides if you are eligible for an immigrant visa.
• Step 6: Notify the NVC of any life changes. You do not need to contact the NVC for routine updates, as they will contact you. However, you must contact the NVC if you change your address, if you were under 21 and have now reached age 21, or if you change your marital status, because these changes can affect your eligibility or visa availability.
• Step 7: Receive your Visa Packet and enter the US. If the consular officer grants your immigrant visa, you receive a sealed packet of information called a Visa Packet. Do not open this packet. USCIS encourages you to pay the USCIS Immigrant Fee online after receiving the packet and before departing for the US. At the US port of entry, you hand the sealed Visa Packet to the US Customs and Border Protection (CBP) officer, who inspects you and determines whether to admit you as a lawful permanent resident.
• Step 8: Receive your Green Card in the mail. Once admitted by CBP and after you have paid the USCIS Immigrant Fee, USCIS mails your Green Card. If you do not receive your Green Card within 90 days of arrival, call the USCIS Contact Center at 800-375-5283 or submit an inquiry on the USCIS e-Request Non-Delivery of Card page.

What the consular officer checks at your visa interview

Whether you visit an American consulate general for a nonimmigrant visa (to visit, study or work) or for an immigrant visa interview scheduled after your priority date becomes current, the consular officer's job is to determine your eligibility under US law.

Because consulates issue visas only to qualified visitors and immigrants, your interview focuses on matching your spoken answers with your petition, your forms and your civil or financial documents. Below are common verification questions officers ask at consular windows, what each question checks and what to have ready.

• What is the purpose of your trip to the United States? For nonimmigrant applicants, the officer checks that your planned activities match the visa category (visiting, studying or working). Be ready to state your exact purpose, destination and timeline in one or two plain sentences.
• How are you related to the petitioner, or what role will you fill for your US employer? For immigrant visa applicants on Form I-130 or Form I-140, the officer verifies that the relationship or job offer in your approved petition is genuine and still active. Have your original civil records or updated employer confirmation ready as listed in your NVC appointment instructions.
• Have your address, age category or marital status changed since your petition was approved? Under USCIS consular processing rules, turning 21 or changing your marital status can alter your visa eligibility or priority category. Always answer truthfully and ensure your NVC file reflects your current status.
• Can I see the original document for this record? Consular officers inspect original civil documents before issuing a visa. Bring the exact birth, marriage or police certificates requested in your interview notice so the officer can inspect them at the window.

Checklist: how to prepare for a visit to an American consulate general

Use this step-by-step plan written by our team to prepare for an immigrant or nonimmigrant appointment at a US consulate, built around the requirements from USCIS and the Department of State.

• 1. Locate your assigned mission in the Department of State's US Embassy and Consulate directory. In large countries with both a capital embassy and regional consulates, confirm which post serves your city or handles your specific visa class.
• 2. Check petition and fee status before you go. If you are immigrating through consular processing, wait until the National Visa Center notifies you that your priority date is current in the monthly Visa Bulletin, your fee bills are paid, and your interview date is scheduled.
• 3. Report any major life changes to the NVC immediately. If you moved to a new address, turned 21, or changed your marital status while waiting for your appointment, update the NVC before your interview.
• 4. Organize your original records. Place your passport, appointment notice, birth registrations, marriage certificates and petition notices in a clear folder so you can hand any document through the window in seconds.
• 5. Follow Visa Packet rules after approval. If the consular officer grants your immigrant visa and hands you a Visa Packet, keep it sealed, pay the USCIS Immigrant Fee online before you fly, and hand the unopened packet to the CBP officer at the US port of entry.

How to find your American consulate general worldwide

The Department of State publishes the global directory of Websites of US Missions and Offices Providing Consular Services on its global mission directory. By our count of the directory, the portal lists 196 country, area and mission entries across its A-to-Z index. This includes 175 bilateral country and territory entries, 12 US missions to international organizations, and the American Institute in Taiwan. The international posts include missions to ASEAN, the African Union, the European Union, the United Nations, and other multilateral bodies.

When you select your country or area from the directory, it routes you to the US mission website for that host nation. That site lists both the capital embassy and every regional American consulate general in the country, along with local contact details for American citizen emergencies, passport renewals and visa scheduling.

• For visa and passport inquiries: The Bureau of Consular Affairs notes that it cannot address individual visa or passport issues through its general website feedback form. Always use your local consulate's website or the Bureau of Consular Affairs website for case-specific instructions.
• For missing Green Cards after arrival: Once you have completed consular processing and entered the United States, your case moves back from the Department of State to USCIS. Wait up to 90 days from arrival after paying the USCIS Immigrant Fee, then contact USCIS at 800-375-5283 or via the e-Request page if your card has not arrived.

Practice example

Has anything changed in your personal situation, such as your address, marital status, or turning 21, since your immigrant petition was filed?

Give a direct, honest answer in one or two sentences that confirms whether your personal details still match the records on file with the National Visa Center. If nothing has changed, state clearly that your marital status and address remain the same as listed on your application and Form I-130 or Form I-140 petition. If a change occurred, state the exact date of the marriage, divorce, 21st birthday, or address move, and confirm when you reported that update to the National Visa Center. Have your original civil documents ready in your hand folder, including your birth registration, marriage certificate, or updated police and address records, so you can pass them through the window immediately if the consular officer asks to verify the record.

Consular officers determine whether you remain eligible for the exact immigrant visa category approved in your petition. Under USCIS rules, turning 21 or changing your marital status can change your visa category or priority date eligibility, so officers check that your current facts match your file.
