we did the same thing for years but we tend to stay here maxing up our visas and extending. But with dtv now it's not possible that's why we need to get the dtv..do the same thing and you are set for 5 years.
I think you are right. That was my worry having done the first 60+30 and returning after 3 weeks while waiting for dtv in HCMC my worry was I won't be allowed in without it. But I still got in with the 60days visa exempt. As long as you are not maxing out the 60 days and not doing a short trip outside seems ok..
I'm sorry I'm not familiar with whatever is the professional mode here
All I know is to post so as to share..I'm not a digital nomad of any sort, just an ordinary person who likes to exchange ideas or oppinions and learn from others. Check my profile if you can see any business related activity.lol!
