Naturalization Cases Involving Outstanding Tax
USCIS notes that naturalization may be denied in the exercise of discretion if an applicant fails to file required tax returns or owes back taxes. Assuming no other negative factors, under what circumstances will USCIS deny an application for naturalization in an exercise of discretion for lack of good moral character where the applicant has filed all required taxes correctly, has a tax debt, has come to a formal agreement with the IRS or other tax authority to repay the taxes owed, and is paying off the debt?

USCIS instructs officers to accept proof that regular tax payments are being made.  USCIS says that all N-400 cases involving an outstanding tax debt will be reviewed on a case-by-case basis, looking at the totality of circumstances.

SSN for Non-working Purposes
I am on H-1B visa and my wife just received her H-4B. She is not allowed to get SSN as this is only for people who allowed to work. I need to get her TIN (TAX Identification Number) but not sure where to start as I have been told she needs TIN for Driver licensing and open Bank account.
