A decent chance, yes. All you can do is try and you'll find out. You did take out the name of your "attendance" provider. If the name removed is that of your current spouse, then the letter is a lie, as she is not in the USA. If you are also outside the USA and she IS taking care of you, she can continue until she gets her visa without expedite.
If it is somebody else in that role, what's the hurry to replace her? This is not clear from what you posted.
