Hi,

I am in California on H1B visa. I am considered a tax resident (spend >183 days in a year here).

I am considering buying a property in Australia (my home country, as defined by Homeland Security)

Can I offset my US income tax with the mortgage interest payment? Would this impact my future green card application? What if I leave the US in the future, do i have to declare capital gains tax one day?

Thanks.
