Do you need a visa for a sailor's passport? !

The local immigration bureau will go to the ship to verify your identity and issue you a landing permit. When you go out in an Australian port, the doorman will check your papers before letting you out. In the United States, you have to apply for a sailor visa and a transit visa at home, otherwise you can't go to the fields when you land in the United States. If you have to go there for a holiday for any reason, the company will hire local police to escort you out of the country. Some countries can't go to each other's ports at all, but they are generally only aimed at the crew of mainland China and Taiwan Province Province, so there is no such problem.
