The LULAC Code is a set of moral principals designed and adopted by the League as its code of conduct and which charges each and every member to:
- Respect your citizenship and preserve it; honor your country, maintain its tradition in the spirit of its citizens, and embody yourself into its culture and civilization.
- Be proud of your origin and maintain it immaculate. Respect your glorious past and help to defend the rights of all people.
- Learn how to discharge your duties before you learn how to assert your rights; educate and make yourself worthy, and stand high in the light of your own deeds;
- Filled with optimism, make yourself sociable, upright, judicious, and above all things be sober and collected in your habits, cautious in your actions and sparing in your speech.
- Always be honorable and high-minded; learn how to be self-reliant upon your qualifications and resources.
- In war serve your country, in peace your convictions; discern, investigate, meditate, think, study, and at all times be honest and generous.
- Let your firmest purpose be that of helping to see that each new generation shall be more efficient and capable.
