USA Amending US Tax Return with ITIN for wife

[thailazer]

I've been married for two years but forgot to get an ITIN for my Thai wife early enough to file 2011 taxes, so I e-filed single. After that, I sent in a W7 form and an amended tax return. I have not heard back and am wondering if they will indeed amend the return and issue the additional refund. The fine print on getting an ITIN says that only a manual return submitted with the ITIN W7 request will do, but this is an amendment. Any inputs out there for me? If I am declined, what recourse do I have?
