1.H1B签证与绿卡在给US政府的交税上有不同？
-If you entered US with H1 visa, you may be qualified for the CHINA-US Treaty to waive the income tax for the first 3 years (as non-resident alien). But if you changed your status to H1 within US, you have to pay the income tax the same way as the green card holder does (as resident alien).
2 resident 与 nonresident的定义有什么区别？
-See above answer in your case. Please note that definition for these two is somewhat different between IRS and USCIS.
3.如果在海外有超过一万美元的银行存款，H1B签证是否应该向US政府申报，其利息收入是否需要向US政府报税？
-Not need. This rule only applys to green card holder and US citizen.
