Just general advice. I may need to send some documents to England. What is the safest, most reliable way, and how long may it take to arrive to UK?
TLDR : Answer Summary
For sending documents to England, DHL is recommended as it takes about 5 days for delivery. Additionally, for sending Thai Baht cash to a UK bank account, using SWIFT payments is a viable option, although it incurs fees from both the sending and receiving banks.
