ANSWER: Thanks to New York DMV, I now know the answer. "If drivers approaching from opposite directions reach an intersection at about the same time, a driver turning left must yield to approaching traffic going straight or turning right."
2. Would J have to give up his British citizenship to become a US citizen with post-9/11 rules? Or can he be a dual citizen?
First of all, this is interesting from the Wikipedia article "Multiple Citizenships":
"- Automatic loss of citizenship if another citizenship is acquired voluntarily (e.g., Azerbaijan, China, Czech Republic, Denmark, India, Japan, Norway). In the case of the Czech Republic two specific exceptions apply: 1. restoration of the Czech citizenship (while keeping the one possessed to date) when the citizenship of former Czechoslovakia was illegally taken away in the years 1948-1990 by the Communist regime, and 2. Czechs as former Czechoslovakians that as of September 31, 1992 had Slovak citizenship causing the automatic loss of the Czech citizenship could apply to regain that Czech citizenship without losing the Slovak one thus becoming dual citizens too.
However, "Many other countries do not recognize the act of renouncing their citizenship as part of US naturalization, so a new US citizen may very likely still be considered a citizen by his old country."
Does the UK?
From the UK Border Agency: "You will not normally lose your British nationality if you become a citizen or national of another country."
Wow. Interesting. So the US has an interesting law where it's like having your cake and eating it too. You can keep your other citizenship but you have to denounce it. I don't think J is going to be up for that. So can he be a permanent resident and work without ever becoming a full US citizen?
I will have to find out later...
