sell shirts like a business and not for a cause and then just maybe you wont be looked at as a charity fraud

Which all comes back to if you have enough income from whatever source why do you have to do fundraisers to pay for Melanie to come to the states. For a wedding... for the baby... just face it... you scammed immigration by telling them you made enough money to support your wife and now baby.
Maybe you told immigration that your fundraising was income.... bet they would like to know that too
