My husband and I are Quimicofarmacobiologos from Mexico. We want to start to work here in Texas. I have read that we need to get a state license to work. Is it an obbligation to work? How can we get that? Do we need to make a test? Where? How?
When do we need to send the school's records to to get an evaluation or revalidation?
Any suggestions are welcome.

I would think you can find out through the Chemist association of your state. Most regulated professions (medicine, engineering) offer certifications, which in some cases are required to get a job offer, or even to apply. Good luck!

Thanks for reply. We are now getting info and more info
