The U.S. immigration system offers a wide range of nonimmigrant visa categories designed for individuals seeking to enter the country temporarily for specific purposes, including employment, education, investment, medical care, or tourism.

 FAQs

  • Processing times vary significantly based on visa type, the consular post, and applicant background. Employment-based visas like H-1B may take months due to cap limits and petition processing, while visitor visas may be adjudicated more quickly, depending on appointment availability.

  • F-1 visas are for academic students attending colleges, universities, language schools, and other academic institutions. M-1 visas are for students enrolled in vocational or technical programs. Each has different rules for work authorization and duration of stay.

  • In certain cases, yes. Some visa holders may apply for a change of status with USCIS, but approval depends on maintaining lawful status, eligibility under the new category, and the purpose of the change. Some visa types, such as J-1 (with a two-year home residency requirement), may require a waiver.

  • No, a business partner is not required. However, the applicant must demonstrate that they have made or are actively in the process of making a substantial investment in a bona fide U.S. enterprise, and that they maintain ownership or operational control.

  • Visa denials can result from issues such as insufficient documentation, inadmissibility concerns, or failure to demonstrate nonimmigrant intent. Legal review may be necessary to assess the reason for denial and determine next steps, such as reapplying or pursuing a waiver.

  • No. Employment is not permitted under a B-1/B-2 visa. Activities are limited to business meetings, tourism, medical care, or attending events. Engaging in unauthorized employment may lead to removal or future visa ineligibility.

  • There is no fixed minimum, but the investment must be substantial in relation to the cost of starting or operating the business. Generally, amounts between $100,000 and $200,000 are considered sufficient, but this depends on the nature of the business.

  • Yes, but the crime must be a qualifying offense under U.S. law, and the applicant must still be able to demonstrate substantial harm and ongoing or past cooperation with law enforcement. Timeliness and documentation are key considerations.

  • No. Premium processing is available for certain employment-based petitions (e.g., H-1B, L-1, O-1) but not for most nonimmigrant visas like F-1, B-1/B-2, or U visas. Availability is subject to USCIS policies and filing categories.

  • Yes, most nonimmigrant visas allow qualifying dependents (spouse and minor children) to apply for derivative status (e.g., F-2, H-4, L-2). Eligibility for work or study varies by visa type.

  • Not always. The two-year rule applies only to certain categories, such as government-funded programs or specialized medical training. If it applies, a waiver may be requested under specific grounds.

  • Generally, no. Engaging in business activity or work while in the U.S. on an F-1 or B-1/B-2 visa is not permitted. Other visa options such as E-2 (Investor) or L-1 (Intracompany Transferee) may be more appropriate for business activity.
