Identify a problem that needs to be addressed and which has an enforceable solution. Research this problem by using the library resources, online resources and consulting relevant profit and nonprofit organizations. Understand other laws relating to the issue at hand to avoid proposing contradicting laws or already existing regulations.
Record your research findings on background information, statistics and the prevalence rates of the problem at hand. Come up with substantial arguments that will support your proposal and find a solution to the identified problem by answering questions, including why the problem is worth pursuing, what opposition you will get to your supporting argument and how you will address this opposition.
Present your findings to community members in form of an organized petition which indicates your proposed law and space for community members to sign. Lobby your friends, family, workmates, community organizers, profits and nonprofit agencies, by explaining to them what your findings mean, the benefits of having a law to regulate or safeguard the issue of concern and take time to answer their questions. Encourage community members to sign the petition supporting your proposed law.
Propose a law or a change to the state law by using the ballot initiative method. File a petition with your local Secretary of State office and wait for your petition to be certified for circulation in the public. Collect signatures supporting the proposed law by mailing the petition or by approaching people in public places such as malls, parks and parking lots to support the petition. Petitions that have enough valid votes are presented to the state authorities to be considered as possible laws.
Schedule a meeting with your congressperson at his office to present the collected signatures and the proposed draft law. In your presentation, first express your appreciation for the congressman's work, and then indicate clearly what your proposed law aims to tackle and propose ways through which you, the community and the congressperson can realize the proposed law.
