The visa situation changes from country to country and I realized I needed a running document to keep track of it all! I wanted to share my list I have made so far with you to help anyone out trying to make sense of it all. Now as always do your own checking as these rules might have changed but this is what has worked for us, being US citizens in 2015.
Australia: An ETA or Electronic Travel Authority is needed to travel to Australia. It is recommended to obtain this 2 weeks in advance although it is typically given automatically. It’s not a stamp, it’s a notice electronically tied to your passport for authorization when you arrive to the country. Passport must be valid for 1 year and once you gain this ETA you can go into the country as many times as you would like for 12 months but you can only remain in Australia for up to 90 days (3 months) at a time.
Brazil: Visa is required for any type of entry for a US citizen. Tourist visas are multiple entry visas and allow you entry for up to 90 consecutive days. The visa is valid for 10 years after issue. You can apply online or at your nearest US embassy. In addition to the visa you need a passport valid for 6 months after arrival, blank pages,
Cambodia: VOA in Phnom Penh, Siem Reap and major border crossings and it is good for 30 days. You need 2 passport type photos (but if you dont have them they will charge you $5 USD and move on), passport valid for 6 months and blank pages. Cambodia uses USD as currency as a majority so you do not need to pay these in riel (the other Cambodian currency).
Canada: No visa required
China: 6 months validity on your passport, blank pages, the visa form and a passport type picture. Also must have proof of itinerary. This means you need a copy of your exit flight and hotel confirmation with your name on it etc. You can get different tourist visas they are as follows; single entry 6 month visa, dual entry 6 month visa, multiple entry 6 month visa, multiple entry 2 year visa, or a multiple entry 10 year visa. All visas are $140 USD for US citizens and you should note going to HK or Macau counts as exit from China so if those are in your plans you should apply for a multiple entry visa. You can apply online for an extra fee or in person at a US embassy near you.
Hong Kong: No visa needed if staying under 90 days. Need 6 months validity on passport and blank pages.
Indonesia: Tourist visa is good for 30 days. You can apply in the US or VOA when you arrive. You must have a copy of your exit/onward ticket to get your VOA, a passport valid for 6 months, blank pages in your passport and it is free for US citizens as of June 2015 (but most websites still say the cost is $35– we did not need to pay for ours).
