Advice(combo or not)

Hey guys just got the messagw that my work auth. was sent by mail and also nov 14 i got message saying my i 131 is approved. My question is- am i getting combo card since both cases approved or it will be seperate? I tried to access onlile pdf file in my uscis account but there is no " documents" option there. It might be because i submitted my case by mail! Please if anyone can advise i would really appreciate it. I really need buy the tickets and fly internationally. Bad news came yesterday that my uncle got cancer...
