回复：小弟实在是新手遇上大问题，因此还请大家继续帮助。请看问题

1、我准备的材料包括：
护照复印件
SN卡复印件
现在H1B签证复印件
3个月paycheck复印件
入境I－94卡复印件
不知道这样是不是齐全了，或者什么东西需要原件？

I hired a lawyer, she took care of everything, But you definitely need new employer's support letter, offer, and finance info.

3、我要拿到新的H1B正式文件以后我现在的雇主才知道？
No need, as long as you file the new application, you are good to leave.
4、看到有人提到什么recipt,不知道这个东西是不是应该比正
式文件早到，是不是拿到这个就可以为新雇主上班了？
The date you put your application into mail box is the day you can start your new job.
X、应该在拿到什么东西之后通知现在雇主我要走人了?
You need nothing before you tell your current employer your leaving.
