I have to say China is pretty tough...have been able to get multiple entry a couple of times now though.US visa has the most annoying requirements. Chinese visa requirements is kind of vague. Schengen visa is ok.
US mahirap kumuha ng visaNot including mga war torn countries
Kakakuha ko lang ng UK visa ko last year and kinaya naman pero nakaka dalawang deny na si US sakin.Not including mga war torn countries
