Xadmin,
Sorry, I didn't read your thread carefully. Since you are changing from H-1 to H-4, it would be in your best interest to attach pay stubs, just to prove the validity of your status. My wife was on F-1 student visa, and I have to submit her practical training (F-1 work permit after degree completion, which is valid for one year)) to validate her status in U.S. INS would have considered her out of status if her PT card was expired at the time of H-4 filing. INS may not ask for pay stubs, but keep it ready in case they do. Or if you want to be proactive send the pay stubs, once you have LIN number assigned to your application.
Good Luck,
