Nonimmigrant Visa

Nonimmigrant visas are intended for foreigners who wish to enter the United States for a limited time and for a specific purpose, such as tourism, studies, temporary work, cultural exchange, or engagement. Unlike permanent residence visas, these visas are not intended for immediate green card acquisition.

B-1/B-2 – Business and Tourism

The B-1/B-2 visa is one of the most common. It covers two purposes:

B-1 (Business): Used by foreigners who wish to enter the U.S. to attend meetings, conferences, negotiations, contract signings, training, or other temporary business activities.
B-2 (Tourism): Intended for tourists who want to visit the U.S. for leisure, vacations, medical treatment, participation in social events, or visiting family members.

Difference between B-1 and B-2:

Although often granted together (as a B-1/B-2 visa), each category has distinct objectives:

B-1 – Business:

- Attend meetings, conferences, or corporate events.
- Conduct business negotiations or contracts.
- Consult with business partners.
- Visit factories or facilities.
- Participate in internal training, as long as there is no service provision or salary received in the U.S.

B-2 – Tourism:
- Leisure travel, sightseeing, and vacations.
- Visits to family or friends.
- Participation in social or cultural events.
- Medical treatments or check-ups.
- Attending courses or educational programs as an observer (without earning credit or a diploma).

Requirements for obtaining the B-1/B-2 visa:

To have the B-1/B-2 visa approved, you must meet several requirements established by U.S. immigration:

Strong ties to the country of origin: It is essential to demonstrate strong ties to your country of residence, such as stable employment, property, studies, family, business, or other factors that prove your intention to return.
Proof of financial resources: The applicant must show they have the means to cover all travel expenses, including transportation, accommodation, food, and additional costs.
Legitimate and temporary purpose of the trip: The intention to enter the U.S. must be clear, objective, and within the purposes allowed by the visa.
Clean immigration history: Those who have had previous visa denials, overstayed in the U.S., or attempted to work illegally may face difficulties.

Required documentation:

The B-1/B-2 visa application process involves submitting various documents:

Valid passport;
Completed DS-160 form;
Proof of appointment and payment of the consular fee (MRV);
Photo in the required format;
Supporting documents showing ties to the country of origin (pay stubs, tax returns, employment contract, school enrollment, marriage certificate, etc.);
Invitation letter (optional) if visiting family or companies;
Proof of travel itinerary (flight reservations, hotels, event schedules, etc.).

Validity and length of stay:

The B-1/B-2 visa is usually issued with a validity of up to 10 years (varies by country).
Each entry allows a stay of up to 6 months, at the discretion of the immigration officer upon entry to the U.S.
In specific situations, it is possible to request an extension of stay for another 6 months, providing solid justification to USCIS.

What is allowed with the B-1/B-2 visa?

✅ Enter the U.S. for tourism, family visits, medical treatment, or social/cultural events;
✅ Attend business meetings, sign contracts, conduct market research, participate in trade shows and corporate events;
✅ Participate in internal training, without receiving remuneration in the U.S.

What is NOT allowed with the B-1/B-2 visa?

❌ Work or receive a salary in the U.S.;
❌ Enroll in courses that grant academic credits or a diploma;
❌ Remain in the U.S. continuously, changing status without justification;
❌ Use the visa for permanent immigration without a formal status change.

Improper use of the B-1/B-2 is one of the main causes of visa cancellation and future immigration barriers. Therefore, it is essential to respect the length of stay, accurately declare the purpose of the visit, and not work or study without authorization.

F-1 – Academic Students

The F-1 visa is a nonimmigrant visa granted to foreigners who wish to enter the United States with the primary purpose of studying at accredited academic institutions, such as high schools, colleges, universities, conservatories, or language programs.

It is one of the most popular visas among foreigners who want to pursue higher education, long-term exchanges, technical programs, or English courses at institutions recognized by the U.S. government.

You may qualify for the F-1 visa if:

You have been accepted by a U.S. institution approved by SEVP (Student and Exchange Visitor Program);
You have sufficient financial proof to cover your studies and stay in the U.S. without working illegally;
You are enrolled in a full-time course;
You can prove your intention to return to your home country after completing the program;
You have sufficient English proficiency or are enrolled in a preparatory course to achieve it.

Required documentation:

Valid passport;
I-20 form signed by the school and the student;
Proof of SEVIS fee payment;
DS-160 form and confirmation of submission;
Proof of appointment and payment of the consular fee;
Proof of financial resources (bank statements, sponsorship letter, scholarship, etc.);
Acceptance letter from the institution;
Academic transcripts and certificates;
Documents proving intent to return to your country (family ties, assets, professional projects).

Validity and length of stay:

The validity of the F-1 visa may vary, but legal stay in the U.S. is determined by the duration of the course, as described on the I-20 form.
Students are allowed to remain up to 60 days after the end of the course and may apply for an extension or change of status.

Work authorization with the F-1 visa:

The F-1 visa has specific rules for employment, prohibiting off-campus work during the first 12 months. However, there are exceptions:

On-campus work: Allowed up to 20 hours per week during the academic term, and full-time during vacations.
OPT (Optional Practical Training): Paid or unpaid internship after completing the course, for up to 12 months (or up to 36 months for STEM courses—science, technology, engineering, and mathematics).
CPT (Curricular Practical Training): Allows internships as part of the course curriculum, with prior school authorization.

Can I change status after the F-1?

Yes. Many students use the F-1 as a gateway to more permanent opportunities, such as:

Changing to a work visa (H-1B);
Marriage to a U.S. citizen and adjustment of status;
Applying for a Green Card by merit or job offer.

Important tips:

Always keep your information updated in SEVIS;
Consult your DSO (Designated School Official) for any changes (course, address, employment);
Do not overstay your permitted time;
Plan your extension or status change in advance.

Religious experience: The applicant must have at least two years of experience working in a religious organization prior to applying for the R-1 visa.

Job offer: The applicant must have a formal job offer from a U.S. religious organization where their religious activities will be performed.
Temporary intent: The R-1 visa is a temporary permit, initially valid for up to 30 months, and can be renewed for another 30 months, totaling a maximum of 5 years.

Benefits of the R-1 visa:

The R-1 visa application process involves completing Form I-129 (Petition for a Nonimmigrant Worker) and submitting additional documentation proving the connection to the religious organization, the applicant’s qualifications, and the nature of the religious duties to be performed. After the petition is approved, the applicant can schedule an interview at the U.S. consulate in their home country.

K-1

The K-1 visa, known as the Fiancé(e) Visa, is a nonimmigrant visa issued by the United States to allow the foreign fiancé(e) of a U.S. citizen to legally enter the country for the exclusive purpose of marriage. This visa is one of the fastest and most efficient ways to reunite couples living in different countries who wish to build a life together in the United States.

Who can apply?

The K-1 visa is available to U.S. citizens who wish to bring their foreign fiancé(e) to the United States with the intention of marriage. To be eligible, the couple must meet the following criteria:

The petitioner must be a U.S. citizen (lawful permanent residents, or “green card holders,” are not eligible to sponsor the K-1 visa).
Both must be legally free to marry, meaning single, divorced, or widowed.
The couple must have met in person at least once in the past two years, with some exceptions for cultural or religious reasons.
There must be a legitimate intention to marry within 90 days of entering the U.S. with the K-1 visa.

Process steps:

Petition (Form I-129F):
The process begins with the U.S. citizen submitting the petition to USCIS (U.S. Citizenship and Immigration Services), proving the relationship and intent to marry.
Review and approval by USCIS:
After review, USCIS sends the approved petition to the National Visa Center (NVC), which then forwards the case to the U.S. embassy or consulate in the fiancé(e)’s country.
Visa application at the consulate:
The foreign fiancé(e) must complete Form DS-160, gather the required documentation, undergo medical exams, and attend a consular interview.
Entry to the U.S. and marriage:
Once approved, the K-1 visa allows the fiancé(e) to travel to the U.S. The couple must marry within 90 days of arrival. After marriage, the foreign spouse can apply for adjustment of status to obtain a green card (permanent residency).

Commonly required documents:

Valid passport
Birth certificate
Proof of termination of previous marriages (if applicable)
Evidence of the relationship (photos, messages, travel records, etc.)
Petitioner’s proof of income
Forms and fees required by USCIS and the consulate

Processing time:

The total time may vary, but the entire process usually takes between 9 to 15 months, depending on the workload of USCIS, the embassy, and the complexity of the case.

ATTENTION:

The K-1 visa cannot be renewed or extended. You must marry within the permitted 90 days.
