i want to go for usa

you need to go to the nearest immigration office or agency that will help you process your papers. it's going to be a long process and an expensive one. but it's gonna be worth it since you'll be getting help from professionals.

which country you presently belongs to?? and there are a lot of ways to go depending upon your financial status and level of education. so first tell about your qualification as well as financual details etc. i hope telling your age will also be helpful to me. one more question is do u have a valid passport??

Dear friend, Do u have the pass port? if u have it, then u can go easly and if u want to stay means u should get the green card and visa.

just do a ticket for the airplane
