both course are good and in-demand or maraming available work for graduates of that particular field kahit dito sa japan. pero kung papipiliin mo ko, mas prefer ko siguro ang computer engineering. pero while studying in this course, i advise you na mag-aral ng maigi ng programming and how to develop ng application in iOS and in Android. ito ang pinaka in-demand now and maybe in the coming future po.
since dito naman kayo nag-aayos ng mga papers ninyo, i think walang magiging problem kahit na japanese pa ang lawyer ninyo. mas better yong naisip mo na dapat talagang meron kayong kasulatan at pa notary mo sa phil embassy po to be sure dahil magiging valid document yan just in case na magkaroon pa ng problem after ng usapan ninyo.
