I should go to America !

I have been thinking about going on a working holiday to America.
I really like America, but the country where Japan concludes an agreement in working holiday is 12 countries there are only twelve countries which I can travel to by using the working holiday visa.

There is not the United States in that. The USA is not one of these countries.
So if I want to go to America, then I will need more money.
But My friend said, "If you really want to go to America, then you shouldn't compromise"
And I realized what which county is the best for me (here you should specify which country, for example: "And I realised that America is the best country for me"). I'm so worried but I still want to try. I will try so hard. Wish me luck.

Good luck! A few things to note: you should try to avoid starting a sentence with "but". It is best to use "However" instead. "But" is better within a sentence.

The USa has such n agreement with Japan
