香港人到韓國開銀行戶口

You cant open a bank account unless you have registered a foreigner ID card. If you only study in Korea for 1 and a half month, you cant have an ID card and therefore, you wont have a bank account.

Take more cash (US dollars) with you and exchange it into Korean Won if you need it.

Or arrange with HSBC for a foreign currency account (no need to buy K-won in HK and no need to have a large amount of deposit in your account) so that you may withdraw K-Won in Korea and the bank will deduct an equivalent amount in HK dollars from that account. HSBC has a branch in Seoul but you have to go to that branch each time when you need money.

可以經HSBC開一個國際戶口,可以在指定國家的HSBC分行提款.但一是要當地有HSBC分行,二是開戶存款數目要幾十萬港元或等值外幣.
不過留學半個月,都唔一定要開戶口,因為淨係用CASH或者信用卡都可以,日常現金可以去銀行換.半個月好快過.你去銀行開戶,得半個月住址證明都無人開到戶俾你.
