Its a pity you cant busk in your country.

I guess one day if you have enough money to travel you could come to the UK and travel around with your hat and guitar and busk here.

You dont need a license or anything like that , you can just travel and sing in the streets.You would probably make back the money you spend to travel here.

Yesterday I watch a couple of films about busking.

This first one is from 2007 ,its called once and its set in Dublin , Ireland ,you can find it here.

This song called Falling Slowly is the main song of the film.I love the melody of it ,you should try and use it for a song,its beautiful.

Here is a good tutorial for it...

The other one is a short film I found on youtube ,its called Buskers.The song the kid is signing at the start is called "Dirty Old Town" Im going to learn it today and make a video later.
