i have too many inquiry in my credit report in last 2 years (there are
about 65).  is there any chance to delete that inquiry from my credit
report within one month?

Unless there is an error, information will not be deleted.

nelson-ga is correct. However, if a bunch of the inquiries are within
a limited time frame (I'm not sure what that is) and relate to the
same purchase (let's say you were shopping for a car and visited 4
dealers over a weekend...and each pulled your credit report), those
are supposed to be read or counted as just one inquiry. So raw numbers
may not tell the entire story.

Second, you may have the opportunity to include an explanation on your
credit report. That's certainly true if you've been denied credit; you
should look into that possibility if there's an understandable (to the
creditors) reason for the large number of inquiries.

Third, if you're planning a major purchase in a month (as your
question suggests), tell the lender up front about the large number of
inquiries and explain why.

Hope that helps.
