I used to have an ITIN now i have a social can i claim the prior year EIC credits? My kids already had socials i was the only one with an itin. I am the primary.

So i know you can claim credits for eic for past years after you obtain a social because its legal and its money that corresponds to you i had family members do this already. I know people who had filed this year 1040x to claim these credits but they received letters mentioning the Tax Hike Act law that was enacted in December 2015. so from what i read that was mentioning you cant claim for dependents who had itin and now social but my case is if i am the primary and my dependents already had social can i still claim this?
