只要以h4身份入境提交ead申请后,是可以离境的。uscis官网faq原文:You may
travel if you are in valid H-4 status and meet all the admission
requirements, including having a valid H-4 nonimmigrant visa. However,
traveling outside of the United States could cause delays in your case.
While you are outside of the United States, we may need additional
information to make a decision on your Form I-765 or we may issue a Notice
of Intent to Deny (NOID) with an opportunity to respond. If you do not
respond on time to a Request for Evidence (RFE) or to the NOID, we may deny
your case as abandoned. Additionally, travel outside of the United States
may also cause possible delays if we need to reschedule your appointment at
an Application Support Center.
