What happens if I don't file Form I-751, and go back to my home country before the 90-days period for good?Do I still have to come to a court hearing?

Although not a guaranteed solution to avoiding court, if you intend to go back to your home country for good, you may wish to write a letter to the California Service Center since you live in Florida and you would be filing an I-751 application to that service center as it has jurisdiction over Florida. You can explain your circumstances, that you will not be remaining in the US, and perhaps give some proof such as an air ticket of your intent to depart. Upon your departure, you can also inform the Center that you have departed and give them proof of such, e.g. copy of passport showing entry into your home country.  The address of the California Service Center for I-751's is:    U.S.C.I.S. California Service, PO Box 10751 Laguna Niguel, CA 92607-1075   Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
