It sounds like you've fallen in love with the idea that coming to Qatar is the answer to helping you find yourself. It looks good online but please be careful. If you don't have a degree, profession or a trade, you will be unskilled labor. Unskilled laborers are not paid well at all in this nation and are not well respected. The American Universities are very exclusive and it would be difficult to get in unless your were a straight A student back home in high school and college and you must have outstanding SAT or ACT test scores. The cost of education here is very high for a foreigner such as yourself. See if you can visit for 2 weeks on vacation/holiday and then see if you can make contacts. You sould then go home and think about it for a while and see what offers come in. Doing labor in 115 F heat is no picnic and you won't be treated well as a common laborer in my view. Consider a U.S. Territory such as Guam -- at least all the U.S. laws will be the same there. Best of luck no matter what you decide. The tourist visa cannot be conversted to a proper working resident visa. You will have to leave while your documents are processed and this can take a month of longer! Remember, be careful and don't make a quick decision.
