謝謝８老師！請問８老師

１）如果舊公司的綠卡排期到了，是否不能用舊公司的I－１４０做H１B延期了？

-Yes, he/she can. But it only can be
extended for one year if the petition is filed when the PD is current. However,
the H-1 extension application can be filed in advance up to 180 days before the
current H-1 expires, so if possible, your friend may ask the employer to file
the H-1 earlier before the PD is current so that the H-1 can be extended for
another 3 years.
 

那麽請問８老師，如果新公司不給辦綠卡，H１B延期隻能延１年，最多允許延幾次呢？能不斷地延下去嗎？
謝謝８老師！
