Please helpe me to correct this letter

Dear Sir


I am planning to bring my wife to here in for one month visit over the forthcoming her annual vacation. (April 15th to May 15th 2010).

I request your good office to issue me a non objection letter to obtain visa from the ministry. All expenses for this visa will be borne by me.

I hope you will favorably consider my request.



Thanking you

Yours Sincerely
