1. He sttes that his parents were immigrants. Not true. Immigration gives one legal residence permanently. I know because I was an American immigrant.
2. He says his parents moved around a lot to stay there. Yes, because they were illegal.
3. He doesn't mention what type of visa he is on or his parents are on. You assume that. An H1 visa will never be extended beyond 6 years, And he has already been in the country 12 to 14 years. So, regardless of what his parents are telling him, they have been there illegally, and I rest my case.
4. A Documented Dreamer is the status of someone who entered the US Illegally. I suggest it is you who looks up the terms and get yourself an education.
