Something to keep in mind here, IF you are a naturalized citizen keep in mind that citizenship is a gift of the U.S. government and can be removed from you (usually only if you commit a felony, but who knows with this administration). Maybe its cowardly, but I would say don’t sign anything of this type if you are a naturalized citizen.
Are you sure? I thought that if you have a green card (legal permanent resident), then you can be stripped of it if you commit a felony. Once you become a naturalized citizen, you are a citizen, period.
