What extra costs would be incurred relocating from the USA to Asia, apart from shipping.?

Answer 1

currency exchange, taxes on what you bring in, and a wide variety of other fees. I would check with that companies worker program policies (or whatever its called now right to work in that country) They will give you a list of do's and dont's.

Answer 2

Where in Asia are you moving to? And from where in the U.S.?

There are locations in Asia (Tokyo, Singapore, and Hong Kong come to mind) where cost of living is on par with more expensive U.S. locations or exceeds it, primarily due to high values of prime real estate.

Children's education can be a concern; getting your child into an English-speaking school can be expensive or downright impossible, depending on where you end up living.

Language barrier may be expensive to overcome; you will need language instruction, but some people just are not good with languages (this is especially true about Asia, where many languages are tonal, which presents enormous pronunciation difficulties for native speakers of European languages), so you may end up needing an interpreter.

Health insurance is going to be a major factor. You will probably want a policy that would pay for medical evacuation, and those are not cheap. Or you can trust the local healthcare system, which may or may not be a wise choice (there is a wide disparity in healthcare quality between different Asian countries; some are quite good, while others are quite bad).

Answer 3

Airfare, hotel to stay in while you look for renting an apartment, transportation.

When you're already there - lots of money will go on buying household things and setting your new home.
