Hi Hansina from Bangladish,
Re: "The offer is quiet fissy…" Sadly, there is on-going not so good news that has been resurfacing on the news recently about the safety of guest workers (in particular) in the middle east. If the job offer is in the middle east, you may want to decline it at this time. The middle east is constantly on the news nowadays---to be a hostile and a dangerous place to live and to work. You would not want to put yourself in harm's way, right? I would recommend looking into China, Korea or Japan for a teaching job---these three countries are offering the same perks and benefits---as I understand from other colleagues. Be very careful where to work these days. Check-out the TESOL Job Seeker's link for English teachers job openings.
