i been having my ssn number but only writing a letter to the IRS to rescind my ITIN. since i just started using my itin number last yr, i was not able to file taxes frm the previous year beacuse i did not make enough. i gave my employer my ssn as soon as i got it. now in order for me to rescind my itin i need to give them a copy of it but i do not have my original itin card. is it possible to just give them a written copy of it?
