How many countries I can visit without visa on usa green card? I know I can go canada, but can I visit europe as well? as us permanent resi?

Each country has its own visa, so your USA visa is for the USA if you wish to travel to Canada you will ( or could depending on your Nationality) require a visa for Canada, the USA and Canada are different countries with different immigration laws/rules.....same as if you wish to travel to China and Japan they are different countries and require a different /separate visa.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
