Be careful, be very careful. I recently met a woman who is divorced, but has custody of her kids. She brought them over with her to live not realising that single woman cannot get visas for children as they cannot be single and have kids. She had to come over saying she was still married, but then was told her husband company must sponser them. It is a long sordid story, but the bottom line is woman are nothing and not recognised as the main breadwinner/sponser, etc. DO YOUR HOMEWORK THOROUGHLY BEFORE ARRIVING
Don't do it, for 500Bd salary, risk , you do not want this. beleive me.
