Extract from Cronian Memo:
"
3. If an H-1 or L-1 nonimmigrant has traveled abroad and was paroled into the United States via advance parole, the alien is accordingly in parole status. Does this interim rule allow him or her to now apply for an extension of nonimmigrant status?
Ans: Until the final rule is published, an alien who was an H-1 or L-1 nonimmigrant, but who was paroled pursuant to a grant of advance parole, may apply for an extension of H-1 or L-1 status, if there is a valid and approved petition. If the Service determines the alien's application for an extension of nonimmigrant status, the decision granting such an extension will have the effect of terminating the grant of parole and admitting the alien in the relevant nonimmigrant classification.
4. If an H-1 or L-1 nonimmigrant has traveled abroad and reentered the United States via advance parole, the alien is accordingly in parole status. How does the interim rule affect that alien's employment authorization?
Ans: A Service memorandum dated August 5, 1997, stated that
an "adjustment applicant's otherwise valid and unexpired nonimmigrant employment authorization ...is not terminated by his or her temporary departure from the United States, if prior to such departure the applicant obtained advance parole in accordance with 8 CFR 245.2(a)(4)(ii)." The Service intends to clarify this issue in the final rule. Until then, if the alien's H-1 or L-1 employment authorization would not have expired, had the alien not left and returned under advance parole, the Service will not consider a paroled adjustment applicant's failure to obtain a separate employment authorization document to mean that the paroled adjustment applicant engaged in unauthorized employment by working for the H-1 or L-1 employer between the date of his or her parole and the date to be specified in the final rule.
The H1 provides both work authorization and the ability to enter the US, and does the work of the EAD and AP. The EAD only provides work authorization and the AP only allows one to enter the US. The Cronin Memorandum seems to say that if you use AP to re-enter the US (ie. don't use the H1 as an entry document), you can still use the employment authorization provided by the H1 petition to work for your H1 sponsor, and the sponsor only.
My guess is that you would still be a parolee or adjustee, not an H1 non-immigrant, but your employment would be authorized for the duration of the H1 petition. Once the H1 petition expired, the Cronin Memorandum says that it can be renewed and an alien could be allowed to switch back into H1 status on its extension if requested in the I-129.
Now what I think you're asking is whether the alien can immediately switch to H1 non-immigrant status after entering using AP. The Cronin Memorandum doesn't address that situation specifically (it only addresses what happens when the H1 expires). But based on my reading of the Cronin Memorandum, I believe that an alien could immediately file an I-539 requesting a change to H1 status based on the unexpired H1 petition.
I'm not sure why one would want to do so. If the I-140 is approved, I-485 denial is rare these days (and I wouldn't travel outside with only AP to get back with if my I-140 wasn't approved and I was doing concurrent filing).
Does that help at all?
Thank you TheRealCanadian for detailed expaination. It clears the doubt as to why one would apply for an H1 extension if H1 itself is NOT nullified by using AP alone. Payrolee can, therefore, continue working for the same employer on whose unexpired petition he was authorized to work. Once H1 expires, One has to apply for an extension or switch to EAD and that is where the need for H1 extension arises.
One Doubt: In US, the status is determined based on I-94. Parole I-94 is usually granted for one year but H1 could be valid for subsequent years. In this case, after the expiry of maximum allowable limit of stay on I-94 (Parole), do we need to do anything to get a fresh I-94 or just wait until H1 expires to file extension and get a new I-94?
Final Rule: Is it published somewhere or Cronian Memo is still valid?
