I will be graduating in May with undergraduate degree in Management. I have been looking for full time jobs during my OPT but havent had any luck so far.

I am looking for some suggestions regarding hourly jobs and places where i can work during my 12 month OPT period. I want to earn as much as i can in a year and finance my graduate studies with that money.

any suggestions and ideas regarding good paying hourly job? if nothing works out there is gas station, but i'd choose working at walmart legally than working at gas stations.

BTW I am in Dallas, Texas if that helps.
