A nonimmigrant visa allows a temporary stay in the U.S. for a specific purpose: tourism, business, study, investment or work. The category should match the plan before travel. People already in the country lawfully can often ask USCIS to extend their stay or change status before their I-94 date passes.
Sound familiar? Parents fly in from abroad to spend a few months with their daughter in Greenpoint, and halfway through the visit they decide they would like to stay longer. Or a family friend who came for a short visit is accepted into a New York school and asks whether classes can start right away. In both cases, the answer depends on how that person was admitted to the U.S. and what their arrival record says.
U.S. law recognizes many nonimmigrant classifications, but a handful come up again and again: B-1 and B-2 visitor visas, F-1 and F-2 student visas, the K-1 fiancé(e) visa, L-1 and L-2 intracompany transferee visas, the E-2 treaty investor visa, and the O-1 visa for people with extraordinary ability. Below we explain how they differ, how the consular and USCIS routes work, and where applicants tend to run into trouble.
Which nonimmigrant visa fits the purpose of your trip?
Purpose always comes first. The B-1 visa covers short business trips such as meetings, conferences or negotiations, while B-2 covers tourism, visiting family or medical treatment. Neither one allows you to work for a U.S. employer or enroll in a full course of study.
Academic study is the territory of the F-1 visa. The school must be SEVP-certified and issue a Form I-20, and the student’s spouse and children may qualify for F-2 status. The K-1 visa is for fiancé(e)s of U.S. citizens who come to the United States to marry. It is technically a nonimmigrant visa, but in practice it leads toward a green card, which is why we cover it in more detail in our guide to family-based immigration and sponsoring relatives.
The next group involves work and business. The L-1 visa is for employees transferred to a U.S. company related to their foreign employer, in a managerial or executive role or in a position that requires specialized knowledge; their family members receive L-2 status. The E-2 visa is for investors from countries that have a qualifying treaty with the United States, and Poland appears on the State Department’s list of treaty countries. The O-1 visa is for individuals with extraordinary ability in the sciences, arts, education, business or athletics.
H-1B specialty occupation visas follow their own set of rules, and we cover them in a separate guide to the H-1B visa for workers and employers.
Consulate or USCIS: which route applies to you?
If you live outside the United States, you apply for a visa at a U.S. embassy or consulate: you complete the online DS-160 form, pay the fee and, in most cases, attend an interview with a consular officer. Students bring their Form I-20 and proof of the SEVIS fee payment. For L-1 and O-1 visas, the order is different: the U.S. employer first needs USCIS to approve a Form I-129 petition, and only then can the worker apply for the visa.
Things look different for someone who is already in the U.S. lawfully. At that point, the visa stamp in the passport matters less than the person’s status and the end date recorded on Form I-94, the electronic arrival record kept by CBP. Extensions and changes of status are handled by USCIS, either on Form I-539 or through a Form I-129 petition filed by an employer, depending on the classification.
The two routes often overlap. Sometimes a change of status inside the U.S. is allowed, but timing makes it more practical to travel and apply at a consulate, or the other way around. The choice depends on the category, past immigration history, travel plans and how soon you need to start school or work. It is one of the first questions to settle during a consultation.
For visitor and student visas, the consular officer will also assess whether you intend to return home after your stay. Documents showing the purpose of the trip and your professional and family ties abroad matter here. Your answers at the interview should be consistent with what you entered on the DS-160.
What determines the cost of a visa case?
The total cost has two parts: government filing fees and attorney’s fees. USCIS fees depend on the form and classification and are adjusted from time to time, so it is best to check the official USCIS fee schedule (G-1055) right before you file. Fees for visas issued at consulates are set by the State Department.
Attorney’s fees depend mainly on how complex the case is. Extending a tourist stay for someone with a clean immigration history is a very different task from a change of status that requires corporate records, an E-2 investment description or the evidence package an O-1 petition calls for. The number of people included in the case matters too, since a spouse and children often need their own forms.
In short, the most expensive application is usually the one that has to be fixed. A denial or a Request for Evidence means more weeks of waiting, sometimes another filing fee, and the stress of watching your authorized stay run out. Careful preparation from the start usually costs less than correcting mistakes later.

How do you extend your stay or change status while living in New York?
Two scenarios are familiar in New York’s Polish neighborhoods. In the first, grandparents who came on B-2 visas to see the grandchildren in Ridgewood or Greenpoint want to stay longer. In the second, a young visitor decides mid-trip to enroll at one of the city’s schools. Either way, the time to act is before the I-94 date, not after it.
USCIS recommends filing an extension request at least 45 days before your authorized stay expires, and that date is the one shown on your Form I-94, according to the USCIS guidance on extending your stay. You must have been lawfully admitted on a nonimmigrant visa, still hold valid status, have complied with its conditions, and have a passport valid for the entire stay. Travelers admitted under the Visa Waiver Program (ESTA) and K-1 fiancé(e)s cannot use this route.
When changing from visitor to student status, one simple rule is often ignored: you may not start classes until USCIS approves the change. That is where things get tricky, because schools run on their own semester calendar and USCIS runs on its own processing timeline. For that reason, people planning to study often also weigh traveling abroad and applying for an F-1 visa at a consulate.
Families need separate attention. The status of a spouse and children, such as F-2 or L-2, depends on the principal’s status, so an extension or change for one person usually affects the others. In many cases family members can be included on the same application as co-applicants using Form I-539A. Each of them still has their own I-94, however, and the end dates may differ if they arrived separately.
What to expect when working with John Nicelli & Associates on a visa case
Visa forms are available to anyone, but choosing the right category and the right sequence of steps takes knowledge of the law and of agency practice. Here is what to expect and what to prepare.
- Experience in immigration law. Visa cases rest on federal law and agency practice that shift over the years. John A. Nicelli, Esq. has practiced immigration law for more than 30 years, and the firm has served clients since 1985.
- An assessment before anything is filed. A thorough consultation starts with questions about the purpose of the trip, your immigration history and your plans. Have your passport, I-94 record and earlier visas at hand, since the category and any potential obstacles are identified on that basis.
- A language you are comfortable in. The forms are in English, but family and work details are often easier to explain in your native language. The firm consults in English, Polish, Spanish and Portuguese, and understanding every answer on the application helps prevent inconsistencies.
- Support across later stages. A case rarely ends with one filing: a student may later change status, and a worker may need an extension. That is why it pays to describe your longer-term plans, not just the next trip.
- A convenient consultation format. Not everyone can get to Manhattan during business hours. Phone and video consultations make the process easier for people outside New York and for those who work shifts.

Which mistakes complicate visa cases?
The first is confusing the visa with the stay. A visa in your passport may be valid for years, yet your authorized stay can end much sooner, because the I-94 date controls, not the visa stamp. The second is entering on ESTA with a plan that requires a different category, since the Visa Waiver Program does not allow you to extend your stay or change status in the U.S.
The third mistake is inconsistency. The purpose of travel stated on the DS-160 and at the port of entry should match what the person actually does and what they later write on applications. Changing plans is not prohibited, but it requires an honest explanation and the proper procedure. The fourth is leaving everything to the last week of an authorized stay.
Overstaying has consequences that reach beyond the current visit. USCIS notes that it can make it harder to return to the United States. That is why decisions about a longer stay or a new purpose are best made while there is still time to file.
A nonimmigrant visa is a tool built for a specific purpose and period of time. The earlier that purpose is defined and matched to the available categories, the fewer surprises at JFK, at the consulate or in correspondence with USCIS.
If your plans change — a longer stay, school, a transfer to a company’s U.S. office — it is best to discuss them before your I-94 date passes. John Nicelli & Associates offers consultations in person, by phone and by video conference. Speak with John Nicelli & Associates: 212-227-8020.
