Here's my draft email, please tell me what you think:
To whom it may concern:
I received the attached refusal letter (Visa Pg.1, Pg. 2, and Pg. 3) on Friday, 31 March 2017. Please see the reason for refusal. There seems to have been a clerical error of some kind. It mentions my two year marriage that took place in Pakistan. I was not married in Pakistan, nor have I ever been to Pakistan. I was married to my U.K. Citizen husband in California over 20 years ago. As evidence I have attached my marriage certificate.
I am asking for someone to review my application, since clearly, there is an error. Please let me know what next steps I need to take to get this cleared up. I am happy to resend any documents you need, along with my passport. If you have any questions, please do not hesitate to let me know. I am anxious to clear this up as soon as possible, as my husband went to the U.K. on 23 March 2017 and I want to join him.
Kind regards,
