"The devil is not as black as he is painted."
I also thought it was difficult, unbearable, etc., but...
Everything went well, don't worry, I'll help.
Again:
Border run - leaving the country and returning to the same country to reset your visa-free stay and get a new stamp in your passport.
Visa run - getting a new e-visa, the same process: leaving the country and returning to the same country to extend your e-visa.
LAOS
border run - 3,600 rubles (approximately, depending on the exchange rate)
visa run - 10,500 rubles (approximately, depending on the exchange rate)
CAMBODIA
border run - 6,700 rubles (approximately, depending on the exchange rate)
visa run - 13,200 rubles (approximately, depending on the exchange rate)
Why is Cambodia more expensive?
To enter Cambodia, you also need a visa; it costs 1 million dong (approximately 3,000 rubles). The reward is shorter lines and no serpentine roads.
People from Muslim countries, I have news for you: if you use the help of "helpers," you'll definitely get to Cambodia, as you won't be allowed into Laos. Don't ask why, no one can answer. You can go wherever you want on your own.
Phew, I helped as much as I could.
