8/24    Question:  I am green card holder and now I want to go back to my
        country.  Do I need to pay uncle sam for the income I earned in
        my home country?
        \_ i suggest you do it anyway, in case you decided to get
           citizenship later.  It's a pain, but generally
           you won't need to pay a penny unless you are making more than
           $84k per year (the figure changes every year, it's slightly above
           $80k/yr).
           \_ is it true that if you are outside of the US for some period
              of time (>6 months), it would jeopadize your citizenship
              application?
              \_ umm, you should talk to your immigration lawyer about that.
