I ALWAYS make a copy or two of my passport, Driver’s License, and Visa before going on any trip, and take photos of everything on my phone. It’s a good idea to keep one in your carry-on and another in your luggage just in case anything ever got lost. I also always make sure to have my Known Traveler Number (KTN) written down somewhere in case I need it – I wrote it in my passport book.
I had only few problems with travelling.
I think it is very important to stay safe while traveling, during my last travel in Europe I had a problem with my date while using Wi-Fi a lot of my data from my Phone and Laptop where stolen. I think you should use VPN while traveling. Some VPN are free and worth using! https://howtogetavpn.com
