He is a US citizen, born and raised in Cincinnati......There is absolutely no question about his eligibility to run for president.
This topic has been discussed here over the years ad nauseum......
I saw a YouTube comment where someone grudgingly gave him credit : "It's a shame when a 'foreigner' (my quotes) running for president knows more about the constitution than Americans do." Made me laugh.
Your link does not give the immigration matriculation date of his parents at all. And you fail to cite '... to US citizen parents' because they seem to have no matriculation date. It's possible they are US citizens, but I've searched for 1/2 hour without finding it. Maybe you can supply their dates of US citizenship martriculation.
