Which Master's degree for H1-B?

Hello,

I recently graduated from James Madison University with a degree in math. I came to US when I was 11 and aged out of my parents green card process so I ultimately had to switch to international student. I was hired at a company temporarily but they will not hire me full time because I would eventually need sponsorship. I am looking to go back to school to pursue a route in technology after heavy research that computer, technology related companies are the main companies willing to sponsor h1-bs. I have about 3 months before I have to enroll or I would be out of status. Please help me determine which master would be good and what city or area would be great to target. Especially people who already had experience working if you know of anyone that went through similar route please share their story with me.
