就無效了。 這時我可不可以重回H1 (朋友可以不cancel H1B)？ 還是又要繳錢重新申請？
-If the H1 approval notice does not expire, you can use this H1 approval notice to go to the port of entry to get the H1 I-94 to reinstate your H1 (if you are Canadian citizen), or use this H1 approval notice to get the H1 visa to come back (if you are not Canadian citizen). But if the H1 approvla notice expire, your friend has to file a new H1 petition for you to change your TD status to H1.
