我是美国绿卡,现在美国大制药公司工作。如果公司派我去中国分公司工作几年,我的绿卡如何保持?请有经验的朋友指点。
-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.
