The most important thing that you should do is to process the legal part so you can be granted a right to stay in the place. You would always have a problem if you will not settle this. That is why it is important to know the process so that you will be able to know what should you do and what to prepare.
The video is helpful as the one who uploads it has the actual experience of going into the process.
