Beware of any offer from a Promise Charity Home School. It is a scam. I was approached for a teaching position there by a Miss Promise Charity in Dubai, UAE. I was given an address to contact by email to get my work permit. I did contact the address, supposedly the immigration office in UAE, but I found that they immediately wanted me to send then US$345 by Western Union to pay for the work permit. That alone is a dead giveaway since no reputable would ask any teacher to send payment for a work permit nor by Western Union. Beware unless you want to lose your money and still have no job.
