do i email coaches or use recruiting agency?

hi, im a 16 year old girl from chile, i graduate in december 2026 and im really interested in playing college soccer in the us (hopefully d1-d2)

i play soccer here in chile but my matches dont get recorded, so my question is if i try to record them (like a highlight video) and send them to the coaches by myself would work (i know this is the typical way to do it, but i dont know if it works the same way with me being from another country)

so i want to know which is the most effective way for me to get recruited, i have no problem with doing it through an agency, i just want to know if they can really get me there because i heard some of them are just a scam

i hope is not too late and any advice would be really aprecciated
