Visas
Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a non immigrant visa for temporary stay, or an immigrant visa for permanent residence. Visitor visas are nonimmigrant visas for persons who want to enter the United States temporarily for business (visa category B-1), tourism, pleasure or visiting (visa category B-2), or a combination of both purposes (B-1/B-2).
Note: Visas are not required for eligible citizens of countries participating in the US State Department Visa Waiver Program. Please consult https://travel.state.gov/content/travel/en/us-visas/tourism-visit/visa-waiver-program.html to see if you qualify for the Visa Waiver Program.
Here are some examples of activities permitted with a visitor visa:
Business (B-1):
- consult with business associates
- attend a scientific, educational, professional, or business convention or conference
- settle an estate
- negotiate a contract
How to Apply
There are several steps to apply for a visa. The order of these steps and how you complete them may vary at the U.S. Embassy or Consulate where you apply. Please consult the instructions available on the U.S. Embassy or Consulate website where you will apply.

Photo
You will upload your photo while completing the online Form DS-160. Your photo must be in the format explained in the Photograph Requirements.
Schedule an Interview
While interviews are generally not required for applicants of certain ages outlined below, consular officers have the discretion to require an interview of any applicant, regardless of age.
If you are age:
| 13 and Younger | An interview is generally not required |
| 14-79 | An interview is required (some exceptions for renewals) |
| 80 and older | An interview is generally not required |
You must schedule an appointment for your visa interview, generally, at the U.S. Embassy or Consulate in the country where you live. You may schedule your interview at any U.S. Embassy or Consulate, but be aware that it may be difficult to qualify for a visa outside of your place of permanent residence.

Review the instructions available on the website of the embassy or consulate where you will apply to learn more about fee payment.
Gather Required Documentation
Gather and prepare the following required documents before your visa interview:
- Passport valid for travel to the United States - Your passport must be valid for at least six months beyond your period of stay in the United States (unless exempt by country specific agreements). If more than one person is included in your passport, each person who needs a visa must submit a separate application.
- Nonimmigrant Visa Application, Form DS-160 confirmation page
- Application fee payment receipt, if you are required to pay before your interview.
- Photo – You will upload your photo while completing the online Form DS-160. If the photo upload fails, you must bring one printed photo in the format explained in the Photograph Requirements.
Additional Documentation May Be Required
Review the instructions for how to apply for a visa on the website of the embassy or consulate where you will apply. Additional documents may be requested to establish if you are qualified. For example, additional requested documents may include evidence of:
- The purpose of your trip;
- Your intent to depart the United States after your trip; and/or
- Your ability to pay all costs of the trip.
Evidence of your employment and/or your family ties may be sufficient to show the purpose of your trip and your intent to return to your home country. If you cannot cover all the costs for your trip, you may show evidence that another person will cover some or all costs for your trip.
Attend Your Visa Interview
During your visa interview, a consular officer will determine whether you are qualified to receive a visa, and if so, which visa category is appropriate based on your purpose of travel. You will need to establish that you meet the requirements under U.S. law to receive the category of visa for which you are applying.
Ink-free, digital fingerprint scans will be taken as part of your application process. They are usually taken during your interview, but this varies based on location.
After your visa interview, your application may require further administrative processing. You will be informed by the consular officer if further processing is necessary for your application.
When the visa is approved, you may pay a visa issuance fee if applicable to your nationality, and will be informed how your passport with visa will be returned to you. Review the visa processing time, to learn how soon your passport with visa will generally be ready for pick-up or delivery by the courier.
Additional Information
- Visitors are not permitted to accept employment or work in the United States.
- We cannot guarantee that you will be issued a visa. Do not make final travel plans or buy tickets until you have a visa.
- Unless canceled or revoked, a visa is valid until its expiration date. Therefore, a valid U.S. visa in an expired passport is still valid. If you have a valid visa in your expired passport, do not remove it from your expired passport. You may use your valid visa in your expired passport along with a new valid passport for travel and admission to the United States.
