(b) Residence. The designation of an owner or first-named coowner is restricted, on original issue only, to persons (whether individuals or others) who are—

1. (1) Residents of the United States, its territories and possessions, the Commonwealth of Puerto Rico, and the former Canal Zone;
2. (2) Citizens of the United States residing abroad;
3. (3) Civilian employees of the United States or members of its armed forces, regardless of their residence or citizenship; and

4. (4) Residents of Canada or Mexico who work in the United States but only if the bonds are purchased on a payroll deduction plan and the owner provides a taxpayer identifying number.

   A nonresident alien may be designated coowner or beneficiary or, on authorized reissue, owner, unless the nonresident alien is a resident of an area with respect to which the Department of the Treasury restricts or regulates the delivery of checks drawn against funds of the United States or its agencies or instrumentalities. See Department of the Treasury Circular No. 655, current revision (31 CFR part 211). Registration is not permitted in any form which includes the name of any alien who is a resident of any restricted area.

(c) Minors.

1. (1) Minors may purchase with their wages, earnings, or other funds belonging to them and under their control bonds registered in their names alone or with a coowner or beneficiary.
2. (2) Bonds purchased by another person with funds belonging to a minor not under legal guardianship or similar fiduciary estate must be registered, without a coowner or beneficiary, in the name of the minor or a natural guardian on behalf of a minor.
3. (3) Bonds purchased with funds of another may be registered to name the minor as owner, coowner, or beneficiary. If the minor is under legal guardianship or similar fiduciary estate, the registration must include an appropriate reference to it.
4. (4) Bonds purchased as a gift to a minor under a gifts-to-minors statute must be registered as prescribed by the statute and no coowner or beneficiary may be named.
5. (5) Bonds purchased by a representative of a minor's estate must be registered in the name of the minor and must include in the registration an appropriate reference to the guardianship or similar fiduciary estate. Bonds purchased by a representative of the estates of two or more minors, even though appointed in a single proceeding, must be registered in the name of each minor separately with appropriate reference to the guardianship or similar fiduciary estate.
