Thanks for your valuable comments !! Appreciate it.

Also, couple of questions if you can help me with.

1. I'll be on the payrolls of the locally Qatari based company (not on the US based MNC) which is just a start up. However they had a grand launch recently where lot of high profile gathering shown interest like ministry of commerce / economy etc. Is it ok to go and join such start up company there ? In india we see every day companies open & close how is the situation there?
2. In any due course of my employment - I have heard usually the employer takes your passport and keep it with himself & force you to work & as per his wish or convenience. Is that true ? Do they ask your passport during any point of time ?

Hope to have some more insights on this.
