My wife has received SSN, she previously had ITIN. I have sent request letter to IRS to
void the ITIN and associate all prior tax information filed under the ITIN with the SSN. Senn letter to:
Internal Revenue Service
Austin, TX [social security number removed]
its been two weeks since i sent letter and there is no update from IRS. Just want to know how long it takes and how to track status of it?
