how can my illegal husband apply for a work visa for now until we get his green card

Hello. If you husband is staturtorily eligible for cancellation of removal he can apply for a work permit before his next court date.  If he doesn't have an attorney for his removal proceeding I highly recommend he gets one as soon as possible.  Removal proceedings are very difficult and effective representation should be sought.
