I was trying to understand the 45 day rule from immigration-law.com:
Sounds like the 45 day rule will apply to labor certs that will be approved in teh future. If your labor cert has already been approved, then no changes to your case? Any thoughts on that?
The substitution labor rule will apply to any I140 that has not been approved yet.
In the final rule making process, there is no comment period before the rule takes effect. On the date when the final rule is published in the federal register, it becomes a binding rule and the rule-making process is complete. Certain provisions in the final rule may take effect on certain specific later date or dates, but the rule itself becomes a binding law on the date of publication of the rule in the federal register. Accordingly, unless the DOL changed the proposed rule, substitution of the beneficiary of the labor certification will be eliminated on the date of publication which includes the substitution of the beneficiary in the pending labor certification by amendment as well as the substitution of the beneficiary in the approved labor certification. For those who filed the substitution I-140 petition, the proposed rule provided that only "substitution approved" on the date of publication of the rule would survive. Substitution approved can be interpreted to mean approval of the substitution I-140 petition. For the 45-day validity of the certified labor certification, under the proposed rule, the certified labor certification on the date of publication was supposed to have 45 days to file the I-140 petitions. For the labor certifications which are approved after publication of the final rule must file the I-140 petitions within 45 days from the date of certification.
