Oh yes, I totally forgot! Okay, here's our timeline:
Entered UK on Visitor's Visa (really only intended to visit): December 15, 2010
Engaged!: December 15, 2010
Applied for Certificate of Approval: December 27, 2010
CoA Approved: February 7, 2011
Married!: April 1, 2011
Mistakenly applied for FLR(M): April 18, 2011
Refused FLR(M) based on visitor's visa: May 27, 2011
Returned to US to apply for VAF4 and submitted online app: May 29, 2011
Biometrics and sent app & docs, priority: June 2, 2011
Email saying they received docs: June 3, 2011
Email stating ours was an exceptional case and could take up to 15 working days: June 8, 2011
Visa Issued!: June 29, 2011 (exactly 15 days!)
So if there's a question that your app will fall under the "exceptional case" category, priority is still absolutely worth it!! Also, we were freaking out that since I left the UK at such short notice, we never had the colour copy of my husband's passport certified, instead he just self-certified and that seems to have been fine (though for sheer peace of mind I would just get it certified next time!)...Hang in there everyone, I freaked out over so many little things and was sure we'd be refused and it turned out I was just being silly! Oh and one more note, UPS totally dropped the ball and didn't deliver my passport and docs overnight as promised, instead we got them the next business day after some furious phone calls with their headquarters! (this wasn't the consulate fault, they sent it next day air, UPS just was lazy or something)
Good luck!! x
