H-1B Visa Extensions
DOL has worked with CIS to set up a new system in the Backlog Elimination Centers to assist individuals who have submitted an application for permanent labor certification prior to March 28, 2005 and need proof of the submission to apply for an extension of an H-1B visa.
Individuals should send an e-mail to the appropriate Backlog Center explaining the need for the H-1B extension and requesting verification that their application is pending at the Center. The email addresses are
h1b7yr@dal.dflc.us for the Dallas Center and
h1b7yr@phi.dflc.us for the Philadelphia Center. Include in this request all pertinent information (employer name and address, alien name and address, date of filing, state where filed, case number, if known).
The Backlog Center will respond to the individual with verification that the application has been pending for 365 days.
