What should I do before returning to Thailand with a Non Immigrant O visa and re-entry permit?

For travelers with a Non Immigrant O visa who have obtained a re-entry permit, there is no specific action required while in the UK before returning to Thailand. It is vital to ensure that your passport is kept safe and accessible.
