This is very common with the immigrants where I live. So many friends struggled with that in their first 3 years or so. They all end up making friends over time, and then the process becomes easier as they meet friends of friends.
There is not a specific method to it. You just hack at it until you find yourself surrounded by friends.
I made friends by connecting with people who worked on similar things. We invited each other for a drink and ended up hanging out. I've also met a lot of friends through other friends. Our groups just merged over time. It helps to be the one organising things and inviting others. I don't remember making many friends in meetups, but perhaps that's just me.
