Very nice finnish for a beginner!

"Haluan siirrä Suomea, niin oppian Suomi"
Literally that means 'I want to move (as in moving the whole finland to a different location) Finland to learn finland'. I think you wanted to say:
"Haluan muuttaa suomeen niin opin suomea"
which is ok as a sentence and right, but I think most people would prefer to say:
"Haluan muuttaa suomeen, jotta oppisin suomea" 

Siirtää=to move something to somewhere (take a pen and move it somewhere) | move something temporally (to postpone a meeting)
Muuttaa=to move from one place to another (a person wants to move to finland) | to change something (To change the color of your hair)

((mahdollisuuksien suomi))
this is quite hard for me to translate into english. Maybe something like 'Finland of opportunities'. Maybe you wanted to say:
Mahdollisesti suomalaisia (if possible finnish)

Hauska tutustua sinuunkin!
