您的情况不一定符合申请H3签证。H3签证对申请人的背景、工作要求其实相对比较细致，一般是要求申请人在美国接受的training在本国是unavailable的（Example: A U.S. company develops a new product for which training is unavailable in another country. The U.S. company may petition to train people to use that product, which will enable the trainees to train others to use the new product in their home country. ）。您也可以看一下移民局关于H3签证的一些详细解释对这个签证类型进行一下更深入的了解：
