Im looking for the oficial list of documents I need to do a tm-87 form. To make non-0 90 day visa, from a 30 day visa exempt stamp. and then the official list of documents for the standard tm-7 application for extension of stay in kingdom. Please no guesses

Depends on which kind of non-o visa and at which immigration office you apply.

Here is a copy of the requirements that I picked up at CM Immigration. I can tell you from personal experience that it is more complicated than it appears. Good Luck with it.
