Marco Rubio was born in the United States in Florida. He is therefore a natural born citizen.
The fact that his parents did not become citizens until several years later...does not affect his status.
See the background of Chester Arthur.. born in Vermont to an American mother and a foreign nationality father.
Marco Rubio has other problems which kept him from being chosen as the VP.
Born to CUBAN NATIONALS!

I am not going to waste my time arguing with stupidity.
Educate yourself...Do some reading. This is to include Chester Arthur about which you are so ignorant.
