Hello Stefizen,

First of all, in Qatar, your salary is tax free
Apart from this, you may get children education allowance, you furniture allowance is not every year, so pls check.

Currency fluctuaction will not much helpful for you as USD is fixed with QRs.

You will get US clubs here, so to have good comfort time.
Apart from your annual leave, you will get 10 days eid holidays( twice a year), so with your Good package, you can easily effort to fly and come back. Ticket cost for economy classes for US is around 1,200USD.

I would suggest to spend a little part of your life in Qatar with QP. I am sure, proper planning will help you to make your retirement for comfortable.
