我需要专家意见－关于是否用EAD或用了EAD后最坏是什么情况。
这是我情况：
我已有EAD，２００７年夏天时FILED ４８５。当时我先生因多种原因没与我同时 filed，所以我们一直在等my PD to be current。现在COMPANY B 想要我转成他们的雇员，这是一家工作很稳定的银行，我很想转。但因他们拿了政府的 funding，他们不能 transfer H１B。我只能用EAD,如果我想为他们工作。我明百如果我用EAD， 我先生就失去了他的H４status. But the H4 is very useful to him. In case of my PD is current, he can enter US as H4 visa, and he can files his AOS the 2nd day after entering, and then he can back to Toronto for his work afte filing AOS。Currently 他是加拿大公民，他每周都回美国。他没有用H４visa 出入，他只是在海关出示 passport。In other words, he enter US as a vistor. My questions:
1. My understanding is that visitor or TN visa holder can file AOS only after 90 days of entering, is this true?
2. Worse case scenario, say my PD turns to current, my application is approved. Can he still file AOS at same time to apply for EAD?
3. How about consular processing? When to file CP request? How long it takes to get green card?
Thanks in advance!
