謝謝8老師回複,yes, canadian citizen but I got my TN vises from US-Mexican border, they stamped to my passport every time with blue oval stamp . it shown the date of entry and expire date of TN.
in 485 part 1, the date of last arraival ( is my new TN visa issued date), Current USCIS status expires on ( not sure is my new visa expired date or the expired date of my old TN I am using it to work?)
看上去有點兒亂, 還望8老師指點。
萬分感謝!
