多谢，关于第二点还是有点晕，能否请sdf老师再解答下，谢谢。

“the intent of I-140 sponsor to hire you still must exist. The burden of proof of such intent is on the petitioner and you. So, the proof you will provide is the promise to rehire/future offer in formal writing. And with the promise of future offer from the sponsor,”
这句话是否意思是“如果pending前换工作，除了要原公司开具继续sponsor的文件？还是只要现在的公司开具能够sponsor offer的文件就行了？”
