What happens if I fall out of legal immigration status?

If you fall out of legal immigration status, you will need to apply for reinstatement as quickly as possible OR leave the United States and return with a new I-20 immigration document (this may or may not require a new visa.) There is no guarantee that a reinstatement will be granted. If you apply for reinstatement while staying in the US and the reinstatement is denied, you are required to leave the United States immediately.
