I'm planning to visit Korea soon and I'm considering opening a bank account there. However, I don't currently have an Alien Registration Card (ARC). Can I still open a bank account without it? If so, what are the requirements and steps I need to follow? I'm also curious about the types of accounts available and any potential benefits or drawbacks. Additionally, would it be possible to manage this account remotely, perhaps through online banking or mobile apps? I appreciate your help in clarifying these matters for me.
