I need help, inaaply ko yung dad ko ng visitor visa sa Canada embassy manila, then we received a letter that he needs to have a medical exam. Then nagpamedical exam ang dad ko sa St.lukes Manila, May x-ray syang dala done 2 mos which was clear and negative of any sakit. Pero pinag xray pa din sya at nirequire sya na mag sputum exam kasi may spot daw, which is nakakapagtaka dahil my dad doesn't smoke or drink at walang history ng tb or something. Tpos ngayun sabi negative daw sa TB pero iculture pa daw and need to wait for 2 mos. Yung letter from embassy is dapat maipasa yung medical within 30 days. what shall we do eh I think in my opinion, wala nmn tlaga spot si dad. need your advices.. thanks in advance..
