How is this even possible?

Short answer.. Singh is a popular Indian name and also one that is adopted by baptized males.

Now imagine if all baptized Christian men adopted Smith as their last name

 

“Majority of the male members of Sikh religion use "Singh " as their last name . As it is mandated in their religion.”

 

No idea, probably just as many as natural born citizens have is my guess.

Personally I can’t go on the attack against Indian people as one of my closest friends is from India. Befriend one and you’ll have a friend for life. Wife also works for an Indian and he is very kind and generous towards her. Lol, just gave her a $14k check just for answering the phone calls while he went to India for a couple weeks.
In short very loving people.

Texas and Florida are among the states that issue these non domiciled CDL’s..shocking, lol.

 

Something you’re not understanding and I don’t know how to explain it.. Singh isn’t their birth surname it’s an adopted name.

 

May as well break everything down by religion because the graph you presented is flawed.
