Jones-Shafroth Act, March 2, 1917 (citizenship)

On March 2, 1917 President Wilson signed the Jones-Shafroth Act, Public Law 64-368, 39 Stat. 951. This lesson's title names the statute and the subject: citizenship. It is not the Merchant Marine Act of 1920. That later Jones Act, section 27, is cabotage, and it is lesson 07. Whoever says 'the Jones Act' on this island without naming a year is mixing two laws.

Jones-Shafroth granted United States citizenship to the citizens of Puerto Rico as a class, with a narrow window for retaining only Puerto Rican citizenship. It also created an elected Senate on the island, kept the appointed governor, and re-established the resident commissioner. The grant of citizenship is statutory. It is an act of Congress, not the rule of the Fourteenth Amendment that makes a person born in a state a citizen. Lesson 29 returns to that distinction. Do not skip it.

A month later, in May, Congress passed the Selective Service Act. The new citizens became draftable citizens. That is the next lesson, not a rumor about why citizenship was granted. The motives of 1917 included war, sugar, and a long campaign by island politicians. The statute's text remains the text. It made citizens. It did not make a state. It did not extend the Constitution by its own force. Balzac will say so in 1922.

Statutory citizenship is citizenship that exists because a statute says so and that a later statute can describe, limit, or re-establish. It is a colder sentence than a naturalization parade. It is also the precise one. People born in Puerto Rico today are citizens of the United States because Congress provided it, now also re-established in the Immigration and Nationality Act, not because the island is a state.

The Library of Congress civil rights guide is the public locator used here, with the Statutes at Large citation. Wikipedia is not the citation. The honesty line is the label. Jones-Shafroth, March 2, 1917, citizenship. Pub. L. 64-368, 39 Stat. 951. Keep that label in the title so lesson 07 keeps its own. Two Jones acts. Two trades. One island that is still not a state.

The numbered finding stays with the public law, the rubric, or the scrutiny. This lesson invents no percentage, no headcount, and no date that the sources of this page do not support. The English terms are glossed in the text so the statute reads without a manifesto.
