isantem, In continuation of your posts in EB3 thread, below information could be helpful in the travel context.
"If I file Form I-131 for a reentry permit while I am in the
United States, can I submit my biometrics while I am
outside the United States?
No. When you file your Form I-131 to obtain a reentry permit, USCIS will notify you when to appear at a designated Application Support Center (ASC) to obtain your biometrics. You must provide your biometrics at the ASC while you are in the United States. If you leave the United States before you provide your biometrics, USCIS may deny your application."
