The purpose of your intended travel and other facts will determine what type of visa is required under U.S. immigration law. Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a nonimmigrant visa for a temporary stay, or an immigrant visa for permanent residence. As a visa applicant, you will need to establish that you meet all requirements to receive the category of visa for which you are applying. When you apply at a U.S embassy or consulate, a consular officer will determine based on laws, whether you are eligible to receive a visa, and if so, which visa category is appropriate.
Visitor Visa
Visitor visas are nonimmigrant visas for persons who want to enter the United States temporarily for business (visa category B-1), for tourism (visa category B-2), or for a combination of both purposes (B-1/B-2).
Business (B-1)
Tourism (B-2)
Travel Purposes Not Permitted On Visitor Visas
These are some examples of activities that require different categories of visas and cannot be done while on a visitor visa:
Visitor visas will also not be issued for birth tourism (travel for the primary purpose of giving birth in the United States to obtain U.S. citizenship for their child).
Student Visa
You must have a student visa to study in the United States. Your course of study and the type of school you plan to attend determine whether you need an F visa or an M visa
Students cannot travel on the Visa Waiver Program or with Visitor Visas
A student visa (F or M) is required to study in the United States. Foreign nationals may not study after entering on a visitor (B) visa or through the Visa Waiver Program (VWP), except to undertake recreational study (non-credit) as part of a tourist visit.
For short periods of recreational study, a Visitor (B) visa may be appropriate.
A visitor (B) visa permits enrollment in a short recreational course of study, which is not for credit toward a degree or academic certificate. Learn more about Visitor Visas.
Study leading to a U.S. conferred degree or certificate is never permitted on a visitor (B) visa, even if it is for a short duration. For example, a student in a distance learning program that requires a period of time on the institution’s U.S. campus must obtain a student (F or M) visa prior to entering the United States.
Student Acceptance at a SEVP Approved School
The first step is to apply to a Student and Exchange Visitor Program (SEVP) approved school in the United States. After the SEVP-approved school accepts your enrollment, you will be registered for the Student and Exchange Visitor Information System (SEVIS) and must pay the SEVIS I-901 fee. The SEVP-approved school will issue you a Form I-20. After you receive the Form I-20 and register in SEVIS, you may apply at a U.S. Embassy or Consulate for a student (F or M) visa. You must present the Form I-20 to the consular officer when you attend your visa interview.
If your spouse and/or children intend to live with you in the United States while you study, they must also enroll in SEVIS, obtain individual Form I-20s from the SEVP-approved school, and apply for a visa (but they do not pay the SEVIS fee).
Temporary Religious Worker Visa
Temporary religious worker (R-1) visas are for persons who want to enter the United States to work temporarily in religious capacities.
As a Temporary Religious Worker, You Must;
For Some Temporary Religions Activity, a Visitor (B) Visa Can Be Used
Certain religious related activities can be undertaken using a visitor (B) visa, such as private worship, prayer, meditation, informal religious study, and attendance at religious services or conferences in the United States. Also, a visitor visa is generally appropriate for ministers of religion seeking to come to the United States temporarily, whose wages and reimbursement will be paid by their own religious group outside the United States, and when coming for:
When you have a religious vocation or profession, or are a religious worker coming temporarily to be employed, with your salary paid by a non-profit religious organization in the United States, the visitor visa is not permitted, and you must have a religious worker (R) visa or other work visa.
Temporary Worker Visas
Temporary worker visas are for persons who want to enter the United States for employment lasting a fixed period of time, and are not considered permanent or indefinite. Each of these visas requires the prospective employer to first file a petition with U.S. Citizenship and Immigration Services (USCIS). An approved petition is required to apply for a work visa.
