1）他准备6月左右跳槽，那时他的H1B还剩1年8个月。那时跳槽还来得及吗？（他的140已批准，跳到新公司后能保住PD，但需重新办申请PERM那些程序）。现在这公司经营状况不好，很可能要再次裁员，我们的排期是2011年5月，听说排期要倒退到07年，所以很担心等不到绿卡就被裁了。所以想着如果来得及就跳槽算了。如果风险太大，就只能赌一赌，留在现在公司等排期。
-If the current employer does not withdraw the approved I-140, he can use that I-140 to extend his H1 beyond the 6 year limit even if he works for another employer.
2）我老公现在的公司正在给他办H1B延期，如果他成功延期H1B 3年后再跳槽，跳槽后这延期的3年会不会废掉。他跳槽后再延期来得及吗？
-He can change noiw and do the H1 transfer using the approved I-140 for another 3-year H1 extension (beyond the 6 year limit) and had better use premium processing to get it approved in 15 days in case the old emploper withdraw the I-140. Then, ask the new employer to file PERM/I-140. Because he has 3 year H1 for the new employer, the time is enough to file PERM and get the I-140 approved. Then, he can use the new approved I-140 to extend his H1 untill he file I-485 or get the green card.
