I entered the US in 1997, my passport with I-94 was stolen in 1998. I applied for a replacement form I-120 and they stated they could not find anything. I came through LAX. I arrived for school with a F-1 visa. The school I went to is a private school, it was sold a few times before I requested for my documents, they could not give me anything other than my transcripts, they stated they requested through storage and could not locate my files (the current school is AIU, used to be ACFAA). The LA campus has since closed but I got a letter from them stating I attended school there. I also do not have my original airline documents and neither do my parents, neither does the airline.
What can I do to get my I-94 located? Do I need a lawyer for this? How much is the cost? Can USCIS find it?Would filing for Form G-639 help?
