关于实习生扣税

我现在全职co-op,想问扣多少税比较合理，我现在每个月的工资都被扣了13%左右，觉得有点多。不知道我可以申请免税吗？毕竟现在还没有毕业。

it doesn't really matter how much they deduct NOW
Just make sure they dont deduct Social Security tax and Medicare from your paycheck (you should only pay it after you get your H1b).
Other parts can all be adjusted when you do your tax return.

13%正常吧 如果是F1可以退5k对应的税 还有州税
除此以外就必需交了

我现在实习几乎都扣19%的税呢。。。想请问这部分税能像学生时候一样退回来起码州税吗？
我现在是OPT
