If you are applying for a nonimmigrant visa to the United States—that is, a temporary visa for business, travel, study, medical treatment, or some other allowable reason—you'll need to plan ahead to make sure it's ready in time for your trip. This typically involves:
Visas to legally enter the United States are processed through the State Department (DOS), via U.S. embassies and consulates around the world.
If you are from a country on the United States's list of "Visa Waiver" countries, you don't actually need a visa to come to the United States for a brief (90-day) trip for tourism or business. You can simply apply through the Electronic System for Travel Authorization (ESTA) and present yourself at a U.S. border, airport, or other entry point. However, it's not ideal for every sort of traveler, particularly if you are hoping to change to another category of immigration status while in the United States.
To learn more about the Visa Waiver Program, and to access the State Department's list of participating countries, go to the Visa Waiver section of the State Department's website.
No matter what type of U.S. nonimmigrant visa you are applying for, you're expected to bring some supporting documentation to show that you meet the basic eligibility criteria and aren't inadmissible to the United States. For example:
Some of the above steps can require weeks or months of planning and communication with U.S. government agencies.
When your are ready to submit your visa application, you will normally make an appointment at a U.S. consulate in your home country. To find out the exact procedures, check the website of your local U.S. consulate. Then, to find out how long you will likely have to wait to get an interview there, go to the State Department's Web page on Visa Appointment Wait Times. There, you will be able to select your country from a drop-down menu and find out typical waits at that consulate for not only the interview, but for visa processing after the interview. Waits of several weeks or even months are not uncommon.
The consular interview requirement can be lifted in certain cases, but this is increasingly rare. The Department of State announced in late July of 2025 that U.S. embassies will greatly reduce eligibility for waivers of the nonimmigrant visa interview requirement starting September 2, 2025, and would expand the in-person interview requirement to include applicants under age 14 and over age 79.
At your visa interview, you (and any accompanying family members) will meet with a U.S. consular officer and present your documentation. Don't expect a sit-down meeting—it's more likely to be conducted through a glass window, and to happen very quickly.
Although the consular officer might give you a provisional "okay" at the end of this encounter, you are unlikely to receive your actual visa on the same day. First, your name, fingerprints, and other biographical information will need to be run through various security and fraud checks.
Assuming you pass the security checks, your visa (most likely in the form of a stamp in your passport) will be delivered to you through a delivery service. Or, you might be asked to return to the U.S. consulate to pick it up on another day. Unfortunately, if you have a common name, or if any questionable information appears on your record, these security checks can take several weeks.
Look carefully at the visa itself. If there are any mistakes, get in touch with the consulate right away.
Pay attention to the expiration date; that is, the last date upon which you can use it to enter the United States. In some cases, this can be in as few as 90 days. If that's not enough time, talk to the consulate about extending it. Also notice whether the visa allows only one entry or multiple entries.
The DOS visa reciprocity tables will tell you more about what length of visas are allowed to people from your country.
If you have any questions or concerns about your eligibility for a U.S. visa, be sure to discuss your options and opportunities with an experienced U.S. immigration attorney, ideally in the state where you plan to enter the United States. Immigration law is federal, however, so an attorney in any state can give you general advice. But if you have trouble at the airport or other entry point, it's handy to be able to call a local attorney for help.
