Hi Zack!
I know this is over a year ago but my husband is in the same exact situation to a T!!! The afghan embassy in UK is complete rubbish. They are communicating with him however and he plans to get a letter too. Any advice you have? What things did you submit and how did your process go. I feel helpless at the moment because we’ve been staying separately due to my job here in the states and his job there. Any help and advice you learned in your process would make a worlds difference.
