Edition Video + Website Maker Hoi An!

Finding a job in VN is like any place else. You need to contact potential employers and apply with CV/resume.

It's unlikely that you will find many teaching jobs in Hoi An. It's relatively small and there are many people already competing for work at the few schools that may be there.

Nearby Đà Nẵng will offer many more opportunities although also a similar level of competition.

Making videos and websites may be a better option but again, many people are doing this including locals.

Either way, you need to go ahead and start networking so that you can see what kind of demand is out there and what your potential options are.

You can post your CV and view ads on https://www.expat.com here:

Always be cautious though. In general, don't agree to anything before arriving as you will want to see with your own eyes what you are getting into. Also, actually being here will open up a lot of new and potentially better opportunities.
