i want to travel 4 to 5 year in the whole world is it possible with one visa if not so then how it possible please guide me Friends?

No it s not possible, each country has visas and each have their own conditions to get that visa and unless you are a multi millionaire no one can go on holiday for 4-5 yrs without working and earning so most countries will not allow you entry as in most you can't work while on a holiday visa

You need visas for each country which requires them. You also need sufficient funds of your own to prove you can provide for all your expenses, including return to your country of citizenship.

its look like if i want to visit 50 country then i need 50 visa :D if i become photographer then it possible ?
