First time filing taxes as an NRA with spouse

So we had our taxes filed and the place we filed at messed up and filed my husband as single where in fact he is not. We quickly had them prepare an amendment as we wished to file our taxes as married filing separately as I currently live and work in a different country and already filed my taxes here, just to avoid confusion.

 

Since it's our first official tax year together I didn't have and ITIN so when we filed for the amendment we also sent my ITIN form to the Austin IRS office as that's where the ITINs are given. I have no US based income and we filed separately.

 

Are they going to give me an ITIN just so we could fix his taxes? Did we do the right thing since filing a joint wasn't the best option for us? How long might it take to see his taxes amended ?
