8老師你好!我的H1b有效期從2015年9月到2018年9月，h1b visa已經過期，現在有回美證，有效期到2017年10月。現在公司想派我到中國工作4個月。請問需要什麽手續？
-No. It is like your regular visiting China.
需要出份文件說明外派我到中國工作麽？
-No, but you need to have the employment verification letter from your employer if you want to apply for H-1 visa to come back.
我還需要在中國申請h1b visa然後入境麽？還是4個月後拿回美證回來就可以了？
-Either one is OK, but it is better to apply for H-1 visa to come back. The company should reimburse the visa application fee for you in your case. So, just talk to the employer about the cost for visa application.
現在有些擔心出境太久入境有麻煩。懇請8老師解答。
