回複：回複：回複：請問140和485可以同時file嗎？

1. 140批準之後再file 485和EAD就可以了,還是需要一直等到current呢?

-Must wait for the PD to be current to file I-485.

2. 我如果想要用EAD就需要先轉成H4,正確嗎?

-No. EAD is irrelevant to H4 or any other non-immigration status.

3. 如果h4後用EAD出境後,需要申請AP回來嗎? (加拿大公民)

-You either use AP or just enter US by getting the H4 I-94 at the port of entry.
