Hi, I studied abroad for my Masters Degree so I can definitely share some of my and my friends’ experience 
This is a very broad topic and there are indeed several factors to consider!
If you’re feeling overwhelmed, I would suggest to start small and take it one step at a time. Most people start with what they want to study – such as a specific program or scholarship. If you know you want to study data science, then you can start searching for different international schools that offer data science programs and narrow it down from there.
Other people naman are more picky about where – if you know you want to study in Japan, then you can start by searching for study abroad programs in Japan and narrow it down from there.
From there, usually the programs have a defined checklist of requirements na for application on their website - that should provide some structure for you as you just have to tick off the requirements one by one. PRO TIP: I have heard so many stories of people getting rejected because they did not follow instructions correctly, like may missing requirement na hindi nila na-submit. This is an easy way to get rejected. Also, process all your applications AS EARLY AS YOU CAN because institutions in the PH tend to take forever to give you your documents and minsan hindi mo ma-control ang timeline nila :((
I could talk more about the process of applying but when you’re there na, the first few months really feel like a dream, parang honeymoon stage. But one thing I don’t see talked about often is the loneliness. There are times where you will feel alone and home sick, tapos you won’t be able to find your favorite Filipino comfort food anywhere 
I would recommend trying to familiarize yourself with the culture if possible before going and deciding if you can live like that for X months. I’ve had friends who left the country earlier than planned because na-realize nila na di pala nila kaya ang language barrier, culture differences, etc.
At the end of the day, I don’t regret going through this experience at all. Because of it I was able to make solid friendships with people from all over the world, learn a new language, and gain relevant academic and work experience and opportunities that I don’t think I would be able to get anywhere else
OK sorry this got really long HAHAHA but I’m happy to chat more about it anytime if may further questions pa <3
Questions: What are important questions to consider? Like visas, scholarships, and housing? Ask away!
