@CarlitosWay , while I agree with @rjs that professional help may be required (depending on your own familiarity with US tax regs on pension ) I would first familiarize myself with (a) tax treaty between US and that other country ; (b) source of the pension i.e. local govt. / social security equivalent in that country, private employer, providend fund or similar , annuity / insurance etc. . etc. etc. ); (c) your own contribution if any etc.
If you need more help on this , please consider providing the above details and I would be happy to help. Note that if you feel that this is not of general interest or otherwise do not wish to put info on this public board , you are quite welcome to PM me and I will come back. In any case , please NO PII ( Personally Identifiable Information).
