I was allowed to stay for 3 mos and I applied for extension. the extension was approved but not on the date i requested. they mailed the letter 1week after my approved date and I received it 11 days late. in short I'm overstaying for 11 days already without my knowledge. I was thinking of applying for a student visa before I got the letter and also thinking of signing the EB2 contract offered to me. Am I qualified to change into either these visa categories? can anybody advise me on the best thing to do? thanks.
