I know this institute well.

If you want to work in Yemen, you have options--but MALI is not one of them. Try Amideast, YCMES, the British Coucncil. MALI is a pseudo-institute run by con artists that thrive on ripping off students and short changing teachers.

If you work for MALI, you will work for paranoid and unqualified management, and they will ruin what could otherwise be a good experience.

So, IMO, go to Yemen, but work for an employer that takes ESL seriously.
