Dear :

I am pleased to learn that I have been chosen for the position of and feel excited about the prospect of working with such a highly innovative company.

The salary and benefits package described in your attached documents are quite close to my expectation. However, because I need more time to make arrangements to move from [place] to [place], I would like to make my starting date [date] instead of [date] as you have suggested.

Could you confirm this date if you think it's acceptable?

Sincerely yours,
