-If you find a job within one month, you may just do the H-1 transfer. Otherwise, you may use EAD to work. Of course, your new employer can file H-1 petition for you any time even if after you use EAD, but the H-1 approval may have no I-94, and thus you need to go to US-Canada border to get the H-1 I-94 to come back if you are Canadian citizen (if you are a Chinese citizen, then you need to go to China to get the H-1 visa).
另外485被拒的话,还能在美国工作吗?
-Yes if you can get the H-1 status.
LD现在是TN, 明年到期,是不是她接下来不能申请TN了?
-Correct. Just use EAD or H-1 to work.
谢谢!
