<human>:  I'm travelling solo in South America soon and I need tips on things like documents to bring, safety tips, and what to expect at the border. Can you help me?
<bot>: For documents, you may need a passport, visa (if required), and proof of onward travel. In terms of safety, it is recommended that you stay vigilant and be aware of your surroundings at all times. As for what to expect at the border, you can expect checks such as questioning your purpose of travel, providing documents, and customs officials may also request you to open your luggage to ensure you are not carrying any restricted items.
