SRE has updated their request form that is required to be used when you want to be a Mexican citizen. They do not want the form hand written and want it typed. I made it a pdf fill in form you can fill in your details and then print copies.
Yes, there is a little bit of shameless advertising for me at the end of the form but I spent the time to create it as many people have had problems typing on the form and had hand written ones rejected. Just type in the form fields and you can erase any info that appears there as well.
The link for the form is http://www.chapalalaw.com/dnn3%20SRE%202015%20Fill%20in.pdf
