Visas

Forgive me if this is already posted elsewhere. I am thinking of doing a safari in Africa that would cross 4 countries and just wondering if a guy would have any problems getting visas with a minor criminal record (minor theft,Dui, and small amount marijuana possession) all charges 22 years or older. Would appreciate any info by anybody similar to this and they're experiences.

What's the problem. Just go to Texas and walk south. Mexico is right there.
