不好意思，我有点糊涂了。
What does it mean when you said "the J-1 application expires"? Does J-1 application has an expiration date?
比如说他的h4 三月底到期，他的J-1五月初approved，那么他必须回国一趟去get the visa stamp so that he could work？ or getting the visa stamp in China is not necessary and he could start to work with his J-1 approval notice (even there is a gap between 三月底和五月初）。 And would this gap be a problem for future green card application?
转J-1身份会有可能被据吗？
