This spring, go to any business you think you may want to work at and get an application. Fast food places have high turn over rates and often hire additional help in the summer. Car places often hire people to help wash cars or deliver them. Check with your local city or town. They often hire summer help for mowing, pools, ball parks, etc. Often local farms will hire summer help. Talk to any family members or family friends who have businesses.
I assume you don t live in USA. So, the first thing you have to do is to get a visa that will allow you to work in the USA. Then, just fill up applications and good luck.
it going to be hard to find a job now. but look on the internet. or cut peoples grass or somthing like that.
start looking now on the internet, in person at local non profit agencies
Good luck finding a job at all.
