The most answers here are over the top. First I would simply avoid ANY connection to BTC, no stickers with BTC logo on your laptop, no keychains, t-shirts, baseball hats etc. It will help you to avoid getting on guards radar. This is especially important if you are visiting countries known for corruption or countries that are in the middle war conflict.
If you are not high profile person that already has unwanted attention of government bodies the risk of confiscating your seed is minimal.
