I recently bought a small residential land in my native country! Do I need to report to the IRS? Since Iam living in here in U.S as resident.? Any helpful tips would be appreciated.. Thank you..

I don't think so.

Your acquiring property abroad by purchase isn't a taxable event with respect to the taxes for which the IRS is responsible, including

income tax;
gift & estate tax; or
excise tax.


So I don't see why the IRS would need to know.
