If we are going to accept any immigrants, your friend is the only type we should currently accept. He came here legally, he is educated, and he speaks English. There is a huge difference between him and the rabble we currently have invading this (once) great nation.
He decided to come to the United States because he believed that the United States would offer more opportunity for his daughters. Furthermore, I believe that he was dissatisfied with the second world atmosphere of Brazil. However, he wanted to be an American above all.
A friend of his, another Brazilian immigrant, I had the occassion to work with. When he arrived, legally, he was all starry eyed. He exclaimed that he "Loved America". I have never seen such a happy guy. He asked me all the time if I "Loved America". He said, "I love this country". He couldn't get enough. I thought, this is the type of immigrant that this country needs. However, he has since gone back to Brazil because of family illness.
