1. 一般情况下,H1B Amendment 需要多长时间可以得到USCIS批准?
-It normally takes about 3 months, but your employer can use premium processing to get it approved in 15 days.
2. 如果提交I485时的状态是H1B,万一I485被据,以后还能申请TN吗(这样的情况是否被认为有移民倾向而不能再申请TN)?
-No. After you filed I-485, you can not get the TN anymore due to immigration intent.
3. 如果既能够在TN状态下提交I485,也能够在H1B状态下提交I485,请8老师给个建议,哪种状态下提交为好。
-It is not different. I-485 filing does not affect your pre-existed TN status. Also, you change your TN status to H-1B any time before or after you file I-485. File your I-485 the sooner, the better if the PD is current in case the PD becomes not current again.
