工卡= Labor Certificate. Not EAD. Foreign People can only work under EAD, H1, OPT EAD(for F1) and GC are all EADs
(1)現在公司就開始申請的話,多長時間可以得到EAD啊?
First. You have to get H1 to work in that company. Once you get H1, you are not neccesary to use 485-based EAD.So "現在公司就開始申請的話,多長時間可以得到EAD啊" has meaningless to u
(2)EAD就是LABOR CERTIFICAE即工卡吧?
No. EAD is not LABOR CERTIFICAE
(3)PERM是否就是用來申請工卡的啊,聽說比較快是嗎?
PERM is for LABOR CERTIFICAE (工卡). Not EAD.
Yes
