Very nice finnish for a beginner!

<em>"Haluan siirrä Suomea, niin oppian Suomi"</em>
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)

<em>((mahdollisuuksien suomi))
</em>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!
