Hi sis, dito ako sa westcoast.
Totoo yung sinabi ng kapatid mo. Hindi ka nya makukuha. At never ka talaga nyang makukuha kasi kapatid ka na lang. Kapatid mo can only get her spouse, kids and sponsor the parents.
Yung parents mo naman can't get you na din because (I believe) you are over 25 na and you're not in school.
The only way for you to come eh mag apply ka on your own. There are ways to do that. Apply as an immigrant (5yrs yata ito), provincial nominee, foreign skilled workers, live-in caregivers, investor, etc.
