Foreign income

I'm a citizen of the U.S. If I move to Taiwan and am employed by Taiwan's company. I need to pay tax for Taiwan for the wage. Do I still need to pay the same income tax in the U.S.?  

 

e.g. if my wage in Taiwan is $100000. if I already paid 30% tax which is $30000 in Taiwan. Do I still need to pay the regular tax rate in the U.S (e.g. 30%)?  That will be total 30% + 30% = $60000.  Or if there is any tax credit or exemption for the income?
