How do i get a job in US?

how do i get to work in an advertising agency or graphic design studios in Washington,US?

A few things. To work for the US, you need a working Visa. The company you want to work for must sign some papers from the immigration.

Or you can try to get citizenship here and be able to work anywhere in the US.

No offense but why in the world do you wanna go to the USA?
You dont want to come here..... trust me on this! Its not a bed of roses that its made out to be, we have just as many problems if not more from where you are from, just sit tight and stay close to your mommma, she loves you and doesnt really want you to go anywhere, keep her happy :)
