Someone has filed a child support claim against me in the USA

I have been in SE Asia for the past year or so working.

I want to go back to America for some family stuff and this person found out somehow and said I was going to get arrested when I got to the USA airport.

The child was born in 2014.

Her and her family are crazy hillbillies and she has threatened my life with her crazy family members coming to kill me.

This is basically what happens when I try to get a DNA test so I can either stop send her money for the child or know if it's my child or not.

She also has not ever let me meet the child.

Would I really get arrested if I went to America now if she filed the child support a few months ago?

Could I just get a DNA test to see if it's my kid or not and then make payments? Or am I getting arrested at the airport?

I just figured out she has told them I havent ever gave her money and I have been sending her money even doubting the child was mine. I didn't keep records on that.

The kid doesn't look anything like me. My other kids all look like my clones.

I actually saw three of the guys around that she was cheating on me with and the kid looks like one of them.

Help
