问题、大鹤您好！我之前有美国H1B工作签证，因为工作了一段时间后就回国了，现在想回去继续工作，可是已经过了六年了，我的H1B还能有效吗？

美国签证找大鹤解答：根据美国移民法，持有H-1B在美国的合法逗留时间通常为六年。在此期间，大部分小伙伴可能会因工作需要或个人原因多次出境。那么，这些在美国境外的时间是否会影响您六年逗留期限的计算呢？其实并不影响，境外的时间不会计算在你的H1B时间内，而且还可以让雇主把你丢失的时间“拿”回来。具体请看一和二。

一、H-1B时间如何回收？

（1）逗留时间的计算方法！

USCIS规定，只有在美国境内作为H-1B受益人的时间才会计入六年上限。在美国境外逗留超过24小时的时间被视为“回收时间"(recapturetime)，而且这并不会计入六年限制。这意味着，你可以将这些在美国境外的时间“回收”，延长你的H-1B身份有效期。

（2）如何回收时间？

要回收在美国境外的时间，需要由您的雇主来提供相关的证明文件。这些文件包括:

1、护照上的入境和出境盖章；

2、1-94入境/出境记录；

3、美国海关与边境保护局的旅行历史；

4、航空机票和登机牌；

5、以及一份详细列出在美国境外逗留日期的清单。

二、USCIS对H-1B时间回收的说明

Q. Does my time outside of the United States count towards my 6-year maximum inH-1B status?

A. Only time spent in the United States as an H-1B beneficiary counts towards the 6-year maximum. Time

spent outside the United States exceeding 24 hours, commonly referred to as “recapture time" or

“remainder time," does not count towards your 6-year limit, and you are eligible to recapture those periods

of time. The burden is on your petitioning employer to request and establish eligibility for recapture time.

Documentation of time outside of the United States may include passport stamps, Form 1-94

Arrival/Departure Records and travel history from U.S. Customs and Border Protection,airline tickets, and

boarding passes, along with an accompanying chart indicating dates outside of the United States.Your

petitioning employer may include such documentation to establish your eligibility for recapturing time

when they submit anH-1Bpetition on your behalf.

Q. I only work in H-1B status for short periods of time throughout the year. 

Does the 6-

year maximum duration still apply to me?

There is not a limitation of stay if your employment in the United States is seasonal or intermittent or for a

total of 6 months or less per year, or if you do not reside continually in the United States.Your petitioning

employer must provide clear and convincing proof that you qualify for such an exception of the 6-year

maximum duration. This proof must consist of evidence such as arrival and departure records, copies of tax

returns, and records of employment abroad.

Q.When can I begin a new 6-year period of H-1B status?

A. You may be eligible to begin a new period of 6 years in H-1B status if you have been outside of the United

States for 1 continuous year, with the exception of brief trips to the United States for business or pleasure. If

you start a new 6-year period of H-1B status you are subject to H-1B cap limitations if your employment is

cap-subject.

美国签证找大鹤提醒注意：回收时间的责任在于您的雇主，但是有的雇主可能并不知道USCIS有这么个规定，所以往往你要自己主动跟雇主提出。另外在提交申请时，也确保提供完整且准确的证明文件，以避免延误或拒绝。
