Even if he is not immediately inadmissible, his chances are pretty slim.

No they are not... Seriously, I really don't know where you are getting your information.

Again - no. He can apply just like anyone else.

If he meets the work experience, education, language and other requirements - he has the same chance as anyone else.

He has no inadmissibility issues - either immediately or later. Please stop making stuff up.
