At work today, there was an emergency situation that required me to leave for Japan tonight for a couple of days. After the initial preparations started, the travel agent realized that i am not a US Citizen and i cannot enter Japan with my green card either. This being a very short notice, there was no time to apply for a tourist visa. So in short, someone else was picked to fly tonight. This made me curious as to which countries allow Green Card holders to enter without a visa. I know Singapore recognizes US green cards in place of visas. If you know of more, pls post so as to spread general awareness. Thanks in advance!!
