You have got to be kidding. Stay in Kuwait. You Indian IT guys have got to stop selling your services so cheap. What is the problem? Do you actually know nothing and just have a paper from a useless university? In that case 3000 RIyals is fine.
DO you have low self esteem? In that case 3000 Riyals is fine.

But if you have brains, good training and are confident ask for twice or triple what they offer and settle! Do not work for free as you will simply waste your valuable life! The ads here were full of household furniture being sold by Indians going home because they were not making money. Food is expensive and inflation is over 10%.

1500 a month you'll be in a bunk bed sharing a bathroomn with 10 men. Shouldn't you have your own room with your own computer and TV so you can work and relax in peace?

Well you are young so you can put up with poor living conditions, but at least make some money to make it worthwhile. 3000 Riyals is not worth it in my opinion. How are you going to get married being poor?

... and they will likely charge you expenses that are not listed in the contract.
