Have been filling my taxes return jointly with my wife living abroad with our 2 Children.
I was able to file jointly with my wife because I requested an ITIN from IRS for her, but I didn't claim my 2 children because they don't have green card and SSN. Now, I have my wife and my 2 Children with me here in USA, they have their green card and SSN.
Could my wife and I amend our 2 years previous tax return and claim our children as dependent?
