If Mexican citizen, get ECA for degree, take language tests, compile job/reference letters from past jobs. Check the CUSMA list and see if your NOC is listed for a LMIA exempt work permit with job offer. Most CUSMA NOCs are professional meaning software engineer as an example. Your degree must match the NOC. So if looking for IT jobs, your degree must be in that field. Once you have job offer then apply for closed work permit at port of entry. So you can apply for jobs but you need to be clear to potential employers that you are eligible through CUSMA.
The IT field has few jobs but if you are highly skilled and educated you may get lucky.
