Moving to HCMC in 3 weeks. Need help!

Vietnam is more safe if you be careful (just some poor thieves) 
You should bring:
1. Your passport
2. Air ticket
3. All of your original certificates
4. Driver's license, if you wish to transfer with Vietnamese Driver's License.
5. Enough money for your expense until you get your pay check!
You can bring dollar. Vietnamese like dollar more than Dong 
When you reach at airport just change little for small expenses.
Almost your queries answered so many times already. Just search from concerned categories.
Here is the Health System

Hi Emiliee,

Which company are you coming to work for?

They should be able to answer all these questions as they should have lots experience in these areas to help new teachers feel at ease moving to a new country.

Good luck with your new journey!

Moving to HCMC in 3 weeks to teach English, and I need a lot of help and advice.

1) vaccinations. Which ones should I get? They are pretty pricey so I don't want to splash out on ones I don't really need.
FYI, 3 weeks isn't enough time to get any vaccine done on time. You need at least a month out. Assuming you're not living in the rural area then you should be fine. Otherwise, typhoid and hepatitis shots require months in advance. You might want to pack malaria medication as well if you are planning on traveling to the country side.

bring a recent criminal background check, original hard copy (no digitals accepted; UK flatmate made the mistake of getting the digital and his local embassy would not authenticate it), signed/stamped/raised seal-- if there's a question of state/provincial vs federal/national -- get both!
