Answer 1

Since you are a citizen of Mexico, you cannot get NAFTA approval on entering the US, as Canadians can. You must apply for the visa ahead of time. Read this:

Answer 2

If you have been refused entry then you must go to an embassy and straighten out the problem, once you have been denied you will keep being denied.
