After you file

Once again the IRS is stretched thin so I would stop thinking in day/weeks and start expecting it to take months ... could be as long as 6 months and not the usual 6-8 weeks.   Once the ITIN is processed they send your docs back with a letter including the ITIN you can use to file the state return if needed.   Then the return is forwarded for manual processing ... check the IRS site once a week for a progress update... it will eventually show up there.
