回复：I140， I485 及配偶申请求助！！谢谢

1。 我太太的LC approve后， 准备同时递交I140， I485， 是否我只要同时递交I485？
You need to be physically present in US for I485 submission. Otherwise, you may go through consular processing to be adjusted outside.

不知我可否以B1/B2的身份递交I485， 是否必须要以H4的身份， 而且人也必须待在美国？
If you have H4, go with H4.

2。 我太太的LC approve后，她的H1 3 年就要到期了，她是否必须申请H1的另三年？
Yes, unless I485 submitted before the H1 expiration and she doesn't want to keep H1.

是否可以申请EAD工作（在她递交I485后），
Sure, but H1 lost, and cannot work between H1 expiration and EAD approval.

如果她需要离开美国出差，必须申请AP， 不知对否？
Definitely.

3。 我可否申请EAD工作， 在递交I485的同时申请吗？
Yes and yes. But using EAD loses your H4.

4。 如果我在递交I485后， 可否会加拿大继续工作？
No. Even if you're in US when filing I485 and may get AP to travel, you cannot stay and work outside US for a long time. But if you go consular processing, yes you can.
