When I mailed my letter, which consisted of at least six pages worth of material, the postal employee said because of the weight I would have to use two first class stamps($.39 a peice). So to be safe when mailing these forms to Carmen make sure that you use two stamps instead of one. Also remember to get the forms notarized by a notary public, for example most DMV's have a Notary Public on staff or you can check your local phone book. Prices range from two to five dollars to have an official document notarized.
