I have a pen pal that is a citizen of Honduras. He would like to come to the US to visit me and our beautiful country. My question is this: if he obtains a 6 months B-2 visitors visa, then maybe half way through, he thinks he would like to move to the US and work here, could he apply for a green card during his 6 month stay. He has no family here in the US, just me, his friend.
That does not sound possible. Green cards to USA are granted based upon very limited basis. But, you should have your friend speak with a lawyer to see what options may exist.
