回复：485面试时要求的税表，是只要联邦税，还是联邦税/州税全要？

Even they just ask the tax form, you should bring everything with you as long as you can remember, such as ssn, passport, f1/j1/h1,bank statement, employment letter, w2, pay slip, utility bill(address proof),......

But, take it easy, you will be fine finally. As long as you preapred, you will get you GC soon.
