kabayan, lilinawin ko lang sana kung ano ba talaga hawak na visa ng misis mo, if residence visit visa yan and not tourist visa/business visa, then it means dito na magstay as resident yung wife mo and you need not get a two-way ticket. Yung term na "visit" sa residence visit visa means hindi talaga permanent as immigrant dito ang wife mo, but since "residence" ang type ng visa nya, it means long term pa rin ang stay nya dito. I suppose husband-sponsored sya under you? :) If not, then I think ordinary visit or business visa lang yung hawak nya and kelangan mo talaga ng two-way ticket para makita ng immigration dito na hindi mag-ooverstay misis mo rito gaya nang naunang sagot ng isa nating kabayan sa itaas. Anyway, good luck sa inyo ng misis mo :)
