I only quoted my full name, date of birth, case number, waiver category (NOS) and then reason for contacting them. Also I indicated my case number and waiver category as the subject of the email.
I submitted my application on June 30th. Everything was updated on the DOS website as at July 7th, except NOS. I contacted them in August for the NOS and they uploaded it and backdated it to July 6th. The waiver is still pending. This week would make it 10th week and I hope I get FR soon.
