RETA certification?

Hi to you all.

Im located in Mexico, in the center of the country, (1Hrr for travel to the Industrial corridor of the country) and currently working in comercial and industrial refrigeration, I want to reach the USA big company's that work in here and for that matter I want to get a licence.

And for that matter I was making a research, I came across of RETA certification,
I have to paid the admission cost and the tests fees, Its seem very detailed, even have some licences for International users as do I.

I have no trouble in to travel to take test, in the USA.

In you experience, since you are in the States, it is the best option for me?

I cant take a months course on the states since I have my own busyness, but I can take ocasional travels to the states to make the examinations.

I will travel the next week, to the SF bay area.

Any toughs or observation will be welcome.
