You are a United States citizen if you were born anywhere in the United States or its territories, including Puerto Rico, Guam and the U.S. Virgin Islands. You are also a U.S. citizen if you were born in another country and then naturalized. 106 C.M.R.§ 362.200
Your may have "derived" U.S. citizenship if you were born abroad and at least one of your biological parents was both a U.S. born citizen at the time of your birth and lived in the U.S. at any time prior to your birth. If both your parents naturalized to U.S. citizenship before you turned age 18, you may also have derived citizenship. See 106 C.M.R.§ 362.210. Check with an immigration specialist if you think these rules apply to you.
The federal and state SNAP rules allow you to self-declare your U.S. citizenship, unless the information you provide is considered “questionable.” 106 C.M.R. §362.210. See What information can I self-declare? Note, U.S. citizenship of children should not be considered questionable solely because parents are immigrants.
