I have seen a a sponsored link in Facebook which named Canada Global Jobs there were details about job openings for hospitality positions. I had tried to send my resume and the link has replied that the reviewed my resume and ask me some questions i answered the details they needed. I am currently working here in dubai. After 2 days i have received an email stating that the my resume was considered and there is an offer letter in it with the position being mentioned. I am not sure if this is legitimate if this is the proper way to employ a foreign worker. They asked some of my documents such as birth cert, copy of my passport and Id's, ther offer is very convincing however they were saying that i need to pay 20% percent of mt.processing fees equivalent to 600US dollars and 80% will be covered by the company for travelling.expenses it.was also stated that they will be giving me 4 years working visa. The email is quite proper but i am not sure if its legitimate. Please help.
