謝謝SCrules, 也謝謝版主親自回答。主要是看到有人這樣說

if you file as a resident, your ssn and medi taxes are waived as long as you registered as a full time student. however, if you dont register for any credit hours during summer sestion, your income during that period of time is subject to ssn and medi taxes.
不知道是什麽依據，也不知道FICA是什麽。
