F Visa

Being turned away at a US airport or port of entry can have significant consequences. Here's what you need to know:
Voluntary Withdrawal: If you choose to withdraw your application for admission, you avoid a 5-year entry ban but may have limited options when seeking to re-enter the US in the future.
Refusal of Admission: This comes with a 5-year ban on re-entry. In some cases, you may be able to apply for a waiver.
Fraudulent Employers: Involvement with any employer who engages in fraudulent activities can lead to a permanent ban on entering the US. It's incredibly difficult to get a waiver in these circumstances.

To avoid these situations:
Be Aware: Stay informed about potentially fraudulent employers. Universities may alert you if they suspect issues.
Consult an Attorney: If you've worked for an employer you now believe to be fraudulent, immediately consult an immigration lawyer. Your level of involvement and when you leave the employer will have a significant impact on your potential liability.
Important Note: There are currently no known successful lawsuits against fraudulent employers in these types of situations.

There are various visa options for entrepreneurs both inside and outside the USA, between non-immigrant and immigrant visas. Non-immigrant options include B-1 for temporary business visits, the International Entrepreneur Rule for temporary parole, and treaty visas like E-1 and E-2. Immigrant visa options include EB-1 for exceptionally qualified individuals, EB-2 National Interest Waiver (NIW) for those impacting US interests, and EB-5 for investors. Overall, EB-2 NIW offers flexibility in job changes within the same field and may lead to a green card without being tied to a specific job or employer.

The grace period after a layoff begins after the last pay period ends, lasting either 60 days or the remaining time on the I-94, whichever is less. Options for extending stay legally include derivative visas (F-1, H-1, L-1), practical training, or applying for a tourist visa (B-1/B-2), with guidance for applying for a B-1/B-2 visa.

Regarding visa rejection misconceptions, rejecting a change of status application to B-1/B-2 within the 60-day grace period does not result in an illegal presence. However, applying after this period without legal counsel may lead to unlawful presence. As for lump sum severance pay, uncertainty exists regarding its classification as regular salary for visa purposes. It's recommended to base the 60-day grace period from the date of stopping work for legal safety.
