Are you saying startups that are from countries who don't speak english are not eligible for YC because they cannot speak perfect english?

I'm definitely not saying that. Y Combinator accepts companies from a diverse number of backgrounds/countries of origin.

Rather, I'm saying that when you apply to Y Combinator, you are competing against the best entrepreneurs around for a very limited number of seats. Since Y Combinator is so competitive, your chances of getting in would be better if you started working with a good writer or editor.
