Law enforcement sources tell us Abby has been transferred from the Victorville, CA prison where she's been since last July. She's now at a facility called the Residential Reentry Center. You could say she's in the homestretch -- she's scheduled to be released May 25.

We're told the facility will provide the "Dance Moms" star with a safe, structured and supervised environment where she'll be given employment counseling, job placement and financial management assistance. Something tells us Abby will have no problem finding a TV gig when she gets out.

Abby was indicted on 20 counts of fraud after prosecutors say she hid $755,000 in income from the government. She was sentenced to a year in federal prison.

Prison's definitely changed Abby, at least physically. She's said to have dropped 100 pounds since entering the pen last July.
