My students wrote the following sentences:

"I request for celebrating my party at your restaurant."
"I request to celebrate my party...."

Nevermind that the constructions are a bit awkward :). Are the sentences correct?

I know that you can "request sth." or make "a request for sth.", but can you simply "request for sth." or "request to do sth."?
To me, the first one sounds just wrong.

I am interested to hear your thoughts.
