New Expat who needs tax advices

I just arrived HK two days ago and will work here for at least several years. However I love the States and will move back several years from now. Therefore I want to keep paying all relevant U.S taxes to avoid legal troubles, while taking all the possible tax exemptions. I've done just a little research so far and it seems like there are two exclusions applicable - the $82,400 income exclusion and the foreign housing exclusion. I am in the legal industry and makes more than the income exclusion. It seems like the housing expense only include deductions for rents and there's a cap at around USD$9000 per month. However, it seems like installment payments are not tax-exempted. I am thinking about buying a property instead of renting (following the advices of Rich Dad Poor Dad), can anybody please give me some advices? In addition, can anyone refer to me any good tax experts on U.S taxation? Your advices are greatly appreciated!

I have sent you a PM with the name of someone I have retained before. There are two or three US tax lawyers in Hong Kong but I quite like this particular one.

Thanks a lot :)

There are US tax accountants in Hong Kong too. However, I am a lawyer too and I find it is easier for me to understand a lawyer than an accountant - especially when it comes to something as technical and tricky as US tax.
