找到一個新公司，辦h1b transfer。家裏有事，需要盡快回國一趟。請問能拿舊公司的h1b I-797辦簽證預約嗎？如果拿舊的h1b預約，新的公司又在辦h1b transfer, 會有什麽問題？
是transfer成功之後，舊的h1b就失效了嗎？
-Depends on whether you still work for the old employer, and if yes, the old H-1 is still valid even if after the H-1 transfer is pending or approved.
一定要用新公司的h1b辦簽證預約嗎？
-Have you worked with the new employer? If yes, you can not use the old H-1 approval notice to make an appointment or use it for the H-1 visa application. If you still work for the old employer, then you can use it to make an appointment, but had better use the new H-1 transfer approval to apply for the H1 visa unless you still will work for the old employer after you enter US.
預約簽證，最快也是1個月後了。有什麽辦法可以提前預約時間嗎
