8老师，实在是感激不尽你的热心肠！解了我燃眉之急！6月份回美后我会继续在A校，直到8月中旬转到B校。那么我的最佳选择就是6月回来后再做A校到B校的transfer是吧？得寸进尺再接着请教：A校的J1到8月中结束，结束之后的一个月内在美都是合法居留的。如果J1 transfer 办理时间较长，9月中才办下来，那么我的合法身份会有什么问题吗？

就是两个J1之间有不到一个月的空窗期。
-J-1 transfer is very quick (normally a few days because it does not need USCIS approval). So,  there must be no gap between the end date of activities at the current institution and the transfer date to the new sponsor. You need to report to the new employer/sponsor within 30 days after the transfer date. Talk to your current employer and the new employer about the J-1 transfer when you start to do it.
