I would like to book a flight to Alaska from Miami while I'm waiting for my green card approval. My lawyer advised me that travel to Alaska is not recommended because we fly over international land and water. But they said its a risk that I can take if I really want to go. Has anyone been in the same situation and taken the flight with no issues? I understand we are flying over international water but I'm staying in the States and don't go through immigration. I don't understand what the risks are. Advice?
