I came to the country in 2004 as F2; in Aug 2007 changed to F1; in Nov. 2007 was changed to H4 (because of an earlier application before F1); in the end of Nov. 2007, changed back to F1.
currently when I prepare I-485, I can't get the I-94 card for Aug 2007 when I went to Mexico to change the status from F2 to F1. Will missing this card matter? what is your suggestion?
Thanks so much. I will file I-485 on Thursday.
