As a British national the good things is i can travel freely in the region without a visa or getting a visa on arrival. So here is a rundown of what Immigration laws i have to abide by in the Region
Malaysia: No visa required. Max stay:90 Days
Brunei: No visa required. Max stay: 90 Days
Singapore: No Visa required Max stay 90 days
Indonesia: Visa on Arrival $10USD for 7 days or $25USD for 30 days
Timor Leste: Visa on Arrival $30USD for 30 days or 3 day transit for $20
Now Thailand is cracking down on illegal western workers. If you cross any Thai border you will only get a max of 15 days in the country. Unless you go visit a Burmese border town. If you land at Bangkok airport you get 30 days MAX.
I require a visa for Laos. I can get a visa on the Thai Lao border for around $35USD, but sometimes its easier to enter a nation when you already have a visa in your passport. The Lao embassy in Canberra gives 30 days visas for $45AUD so thats roughly the same prices in currency but at least you don't have to pay a scammer or a tout.
From what i have heard when border crossing in: Lao, Cambodia or Vietnam you got to pay a greenback or to as a Stamp fee. Its not much of a bribe i guess.
Vietnam requires a visa before arrival. So ill have to visit the consulate in June to apply for one. A Vietnam visa has a validity of 3 month and a stay for 30 days max i assume. You can get a Vietnamese visa on arrival at the major airport but you need one to cross any of the borders
Cambodia embassy in Canberra does give out 30 day tourist visa, but it costs a lot more than getting it on the border. Johnny from dontstopliving.net reported that the cheapest cost to get a visa on arrival in Cambodia was $26USD. its $25 for a cambodian visa and a few extra greenbacks to pay to exit Laos on a weekend or as a stamping fee.
Don't pay anyone $30 to get your visa from a tout. Only pay $25 to a Cambodian immigration officer. As i am yet to enter Cambodia, i know well in advances what to do. Its like the time some asshole in Tangier wanted to fill out my departure card. I already filled it out before i left Spain and the whole form was in English. So don't ever pay anyone to fill out a form.
Myanmar (Burma). The Burmese embassy in Canberra issues visa in a turn around period between 10 days to 4 weeks. Since i really want to see Rangoon and not a Thai Burmese border crossing I need to get a visa from the embassy in Canberra. I'm sure it will be cheap and won't cost more than $40.
When less developed nations start issuing E Visa, then there won't be any more waitings for visas.
Also as a British citizen i can visit: Philippines, Hong Kong, Macau, Taiwan, Japan, Republic of Korea without having to pay a cent. In Hong Kong British Citizen can stay for up to 180 day but are not allowed to work without a permit.
As soon as i am issued my next visa, a guide will come out on how to get a Vietnamese, Lao, Cambodian & Burmese visa
