I'm applying for my 90 day visa online. As of right now, I haven't yet made my final date to travel. What can I do? I don't have a hotel booked yet either. Am I stuck until I have the exact date? It will be based on when I sell my home, so I don't know yet. Also, it asks for last port of embarktion. Do I use my home airport of the conecting airpot just before arrival?
