请教皮匠及八老师一个问题：
I am practicing medicine in US. Last year I just got my J-1 waiver and then my hospital sponsored me H-1B visa. After several months, I decided to apply for green card via NIW category for foreign physicians (underserved area with a 5-year limit). So far my 1-140 has been approved and 485 is pending. I was also approved 2-year EAD. Now here comes the problem: I want to do some ‘moon-lighting’ (using my EAD for other hospital to earn extra money), but my employer hospital informed me that once I start to use the EAD, I will lose my H1-B. Is that true? I am not sure if the hospital told me the truth. Please advise me in this matter.
感谢之至！
