Thank you so much for your advice. I have been to INS local office for 4 times but can not get result. Every time they show bad attitude to me. Last time when I went to there, a guy told me they can not input my information because they are local office. So I write a letter to London, Kentucky to ask them to input my information. But international office suppected that it works. I can do nothing now. I can not go to other country to get my I-94 information input because my visa has been expired I do not want to risk myself. It is so regret for me not to ask for your help earlier. No one around me told me I can get my I-94 input by visiting other country. Is it possible to ask for help from a lawyer and ask them to contact INS directly? Thank you again for your help.
