我是美國綠卡,現在美國大製藥公司工作。如果公司派我去中國分公司工作幾年,我的綠卡如何保持?請有經驗的朋友指點。
-get the Reentry permit (RP) which allows you to work in China for up to two years. Then, come back to US to get another RP before reaching two years, and so on. If you want to use the time you spend in China as the physical presence for your US citizenship application, you can file N-470, Application to Preserve Residence for Naturalization Purposes in addition to the RP. See the N-470 Instructions at USCIS website.
