No SS#, Cash pay, Student Seeking Job in Houston (( Help))

Hello friends, I am 21yr old female seeking desperately for a job in Houston. At least til May. I am living here on an F1 visa so I shouldn't be working until I request for a job visa. After suddenly having to make plans to move out by may I now desperately need to start saving money. I have a job but I am not getting any work hours currently. Does anyone have any advice? Any openings for someone like me would be awesome. I live near the down town and I am down for anything that isn't physically taxing due to my health. I have some good experience in different areas and even then I learn fast. Thank you.
