I saw quite a few posts about people having missing addresses, emails, etc, particularly on family forms. While I can’t say whether they will return an application for these types of mistakes, just some info for further reference.
When it comes to family, we only put email addresses for my husband’s family for members over the age of eighteen. We included all addresses except one because we did not know it. Anytime you do not know an address or email simply add a separate sheet of paper explaining why that is the case. We had no issues by simply providing an explanation for the one missing address.
It is always important to double, triple, quadruple check every page of your application before sending it in. It’s always good to do it on separate days because that’s when you will often catch something you missed the day before.
I hope nobody has an application returned, but if it does happen keep this mind for when you send it in again!
