我想请问一下，在申请 PERM (EB2) 的过程中，我能否更换律师？如果可以，应该注意些什么。如果不可以，能否在 PERM 获批之后更换律师？谢谢。
Is it possible to change my lawyer (from my company) during the process of applying my PERM (EB2)? If so, what should I do? Otherwise, can I change my lawyer after the PERM application is finished, or any other time during the process? Thank you for any information. Appreciate it.
