1.綠卡持有者在中國高校的收入要交稅嗎？
-Yes, you need to file the tax return (1040) to pay the tax to IRS as you have the imcome in U.S., but you may deduce the amount of the tax you paid to Chinese Government as the tax credit for your tax to IRS in U.S. Contact IRS for the details. If you do not file the tax return to pay the tax, your lawful permanent residency will be cancelled.

3.交稅後算security credit points嗎？
-Yes, of course.
