The argument is similar in spirit to the Unabomber's manifesto, though argued in a more abstract realm. Skrbina guesses that his pen pal would not be interested in that work. He's such a practical thinker that things like this he probably considers a waste of time.
Every U.S. Citizen/landed immigrant wishing to travel to China must submit a China visa application. No traveler, including business and pleasure travelers as well as students, will be admitted to the country without a China visa. How far in advance should I apply for a China visa? You cannot apply any further in advance of your trip than three months. It is highly recommended that you apply no later than three months in advance of your intended departure date. The more time you can allow for processing of your application, the better.
A Vietnam visa application can be applied for 1 day to 6 months in advance. Although it takes only 2 working days to get your visa approved, it is strongly advised that you apply for a Vietnam visa 1 â 2 weeks before your arrival date to avoid any unexpected payment issues or other administrative problems.
