1.H1B簽證與綠卡在給US政府的交稅上有不同？
-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 與 nonresident的定義有什麽區別？
-See above answer in your case. Please note that definition for these two is somewhat different between IRS and USCIS.
3.如果在海外有超過一萬美元的銀行存款，H1B簽證是否應該向US政府申報，其利息收入是否需要向US政府報稅？
-Not need. This rule only applys to green card holder and US citizen.
