I am on probation and I want to travel to Mexico. What do I need from my p.o to Travel.

Permission to leave the country, which I doubt you'd get while on probation.

Is there a Travel Pass you have to get from your p.o to Travel.

You'll have to check with your PO ; every jurisdiction is different. What do the conditions of your probation stipulate? But frankly, I think the odds of my winning the lottery are greater than the odds of you being given permission to leave the country while on probation. I could be wrong and it never hurts to ask but I'd be shocked if you actually got OKed to travel outside the country.

Under Standard Conditions of the probation. I have to get permission if I am living the state for more than 24 hours.

Then there's your answer, right there.
