You can't just sign up to the big companies and expect them to just instantly give you access, you have to be really experienced in game design and prepared with previous projects for PC, iOS, Android, etc.
They will want to see proof that your aren't someone who looks shady and random, and willing to steal/leak their tools and SDKs. Not that I am accusing you of wanting to do that; I am pretty sure you will not do that, lol.
By the way, I just looked on
Sony's developer sign-up site and it looks as if they do have European support through SCE Europe. But I'm not really too sure how it works, and it's off-topic anyway.
