I have just read the following on 2nd paragraph of page 3 of HQBCIS 70/6.2.8-P dated Aug 04, 2003. This can be found at http://uscis.gov/graphics/lawsregs/handbook/I140_AC21_8403.pdf which states:
"Accordingly, if the employer withdraws the approved Form I-140 on or after the date that
the Form I-485 has been pending 180 days, the approved Form I-140 shall remain valid under
the provisions of §106(c) of AC21. It is expected that the alien will have submitted evidence to
the office having jurisdiction over the pending Form I-485 that the new offer of employment is
in the same or similar occupational classification as the offer of employment for which the
petition was filed. Accordingly, if the underlying approved Form I-140 is withdrawn, and the
alien has not submitted evidence of a new qualifying offer of employment, the adjudicating
officer must issue a Notice of Intent to Deny the pending Form I-485. See 8 CFR
103.2(b)(16)(i). If the evidence of a new qualifying offer of employment submitted in response
to the Notice of Intent to Deny is timely filed and it appears that the alien has a new offer of
employment in the same or similar occupation, the BCIS may consider the approved Form I-140
to remain valid with respect to the new offer of employment and may continue regular
processing of the Form I-485. If the applicant responds to the Notice of Intent to Deny, but has
not established that the new offer of employment is in the same or similar occupation, the
adjudicating officer may immediately deny the Form I-485. If the alien does not respond or fails
to timely respond to the Notice of Intent to Deny, the adjudicating officer may immediately deny
the Form I-485."
So changing employer using AC 21 is safe. Infact I am doing it next week.
Cheers,
IJ
