我是加拿大公民持H1B Visa在美国工作，公司正在帮我办绿卡， 请问8老师几个问题
1。 公司目前正在申请PERM labor certification, ，我l另外还需要找律师帮我申请绿卡吗，还是让公司做，我什么也不用做，等就可以？
-It seems your company has hired a lawyer to handle the case, so you don't need to waste money to hire another one.
2 PERM labor certification批准以后， 我就可以在美国工作， 不需要工作签证（我的H1B Visa 明年到期），对吗？
-You need to renew your H-1B to continue your work.
3。 我家人可以一起和我申请绿卡吗？
-Yes.
如果可以，他么什么时候申请？，
-When you file I-485, your dependents can file their I-485 with you if they are physcally present in US at that time.
他们需要到美国吗？ 他们目前在加拿大，不想目前到美国。
-They can come to US to file I-485 together with you when your priority date is current in the future, not need to come here now.
