Well, you might as well start with the fact that unless you are already married, it would be illegal for you to live together. You will also run into trouble with sponsoring the child, unless he/she is from a previous marriage, for which you can show a divorce/death certificate. 4,000 QR is really not much, especially if you have an apartment (and especially two) and schooling for the child to still pay for. Both costs are astronomical here. School fees alone range from 30,000 QR to 50,000 QR. Apartments - about 5,000 QR. You will also need a car, as public transport is not much of an option. I suggest that you either look for other employment, or strongly reconsider.
