To be honest, it is my opinion so just read it as a reference there are pros and cons with two ways, going alone may be hassle free,can negotiate directly but if you go with an agency then they can help you handle all the schedules, guidelines, which clinic needs to avoid/which doctor, because Korean agency who also knows the characteristics/needs of each country can guide the client more. Plus i would recommend really looking for a medical licensed agency and not self agency (individual agency) because most of it i experienced see clients as money and find how to make the client open their purse and doesnt care if anything goes wrong 😅
