"Anything specifically addressed to the ECOs will not returned. Nor will the application or biometrics sheet. For me, they also kept the contact records we submitted, and I am vaguely recalling that they also kept the certified copies of my sponsor's passport and birth certificate."
My bank statements aren't addressed to the ECO's though...my bank sends me bank statements, I keep them for my records with the IRS, etc. I sent statements since the beginning of this year, I didn't know I wasn't going to get them back...I feel like that's not right. I figured the application and biometrics wouldn't, cos those pertain to the visa and consulate only, I don't need those further down the line in life. People have always told me to retain bank records for 7 years in case of audit...I am now missing a chunk of time because they were not returned to me?
