How do the prepositions 'to' and 'of' change the meaning of the word 'considering'?
1) considering to
2) considering of
What's the context?
But is it possible to use them in those sentences?
No
Context is always important; labelling is rarely important.
[Thank you, bhaisahab! You are probably right--it's just that saying the words back to back sounds a little off to me, but then again I'm no expert in being able to tell the difference between correct and incorrect. So, alternatively are these two correct:
1) considering applying to...
2) considering to apply...

As a native speaker, I simply can't hear myself putting any kind of preposition after "considering". I would always use a participle or noun (He's considering applying to Stanford/ He's considering his options.). However, "consideration of" and "consideration for" are phrases you're likely to hear.
