Many thanks for your help!
申請了consular processing. 現在又有問題:
1. consular processing肯定得幾個月時間吧? 有了 這個I-140 approval, 我還能去Port of entry 給家裏人拿H-4嗎?
-Yes, it is irrelevant to H1/H4.
我現在是H1-b, 住在加拿大,想現在就搬家(免得兒子中間換學校)。H類都是非移民的, 現在我已經申請要移民了,會不會不給H-4呢?
-No problem at all.
2. 我的h-1b明年一月到期。 現在還是申請extension嗎?
-You had better get it extended until you get the GC because you use consular processing and thus, you can not have EAD.
