How long was your wife in the UK? Did she do anything else to prove her residency? Did you write anything fancy in your cover letter?
She was in the UK for 7 months with the visa, 13 months if you include the 6 months as a visitor without her visa.
She didn't do anything else to prove her residency,(other than have an address in the UK). We did have to list my wife's residence for the last 5 years on the Biographic Information, but we included the six months she was here as a visitor without a visa.
Didn't write anying fancy in the cover letter!
You may have to explain why she was here such a short time if they ask, that is the only thing they may question, but Brooke had no problem and she wasn't here all that long.
