It is true that unless you are only in USA for 30 days of the year, you will still have to pay income tax in USA. I've been in Asia this year, working as remote freelancer and because I had to come back for about 6 weeks to deal with some business stuff, I won't be able to claim the foreign income tax excludion. I'll also have to pay the ACA penalty (still cheaper) because I cancelled my health insurance after leaving USA. But living in Asia has been a great experience and I would recommend it. However, time zones between here and west coast are weird. I'm either waking up at 5am or staying up til 12am if I have to do a call.
