回复：回复：回复：请教8大师，P大师和各位大侠们，H1B第六年 140已批 可以换工作吗？？

谢谢您的回答，那么如果新公司开始transfter/extend 我的H1B，现任公司有可能会知道吗？

-No. But after you leave, the employer might withdraw the I-140 if they are not happy though most employers do not care and not withdraw it. You have to prepare for the worst case even if your current employer may not care about it and may not withdraw the I-140..

他们是否会通知现任公司？

-No. Irrelevant.
