谢谢8老师回复，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.
-That stamp is entry stamp (I-94), not visa stamp. To get a visa stamp, you have to apply for the visa in a US Consulate by submitting DS 160..
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?)
