Clause 2: Qualifications of Members.

No Person shall be a Representative who shall not have attained to the Age of twenty five Years, and been seven Years a Citizen of the United States, and who shall, when elected, be an Inhabitant of that State in which he shall be chosen.

The Constitution provides three requirements for Representatives: A Representative must be at least 25 years old, must be an inhabitant of the state in which he or she is elected, and must have been a citizen of the United States for the previous seven years. There is no requirement that a Representative reside within the district in which he or she represents; although this is usually the case, there have been occasional exceptions.

The Supreme Court has interpreted the Qualifications Clause as an exclusive list of qualifications that cannot be supplemented by a house of Congress exercising its Section 5 authority to "judge...the...qualifications of its own members" or by a state in its exercise of its Section 4 authority to prescribe the "times, places and manner of holding elections for Senators and Representatives." The Supreme Court, as well as other federal courts, have repeatedly barred states from additional restrictions, such as imposing term limits on members of Congress, allowing members of Congress to be subject to recall elections, or requiring that Representatives live in the congressional district in which they represent. A 2002 Congressional Research Service report also found that no state could implement a qualification that a Representative not be a convicted felon or incarcerated.

However, the United States Supreme Court has ruled that certain ballot access requirements, such as filing fees and submitting a certain number of valid petition signatures do not constitute additional qualifications and thus few Constitutional restrictions exist as to how harsh ballot access laws can be.

Finally, although the U.S. Constitution places no restrictions on state or local office-holders simultaneously holding federal office, most state constitutions today effectively ban state and local office holders from also holding federal office at the same time by prohibiting federal office holders from also holding state and local office. Unlike other state-mandated restrictions, these sorts of prohibitions are constitutional as long they are enforced purely at the state level (for example against active federal office holders seeking to obtain or hold a state or local office).

Clause 3: Apportionment of Representatives and taxes.

Representatives and direct Taxes shall be apportioned among the several States which may be included within this Union, according to their respective Numbers, which shall be determined by adding to the whole Number of free Persons, including those bound to Service for a Term of Years, and excluding Indians not taxed, three fifths of all other Persons. The actual Enumeration shall be made within three Years after the first Meeting of the Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law direct. The number of Representatives shall not exceed one for every thirty Thousand, but each State shall have at Least one Representative; and until such enumeration shall be made, the State of New Hampshire shall be entitled to chuse three, Massachusetts eight, Rhode-Island and Providence Plantations one, Connecticut five, New-York six, New Jersey four, Pennsylvania eight, Delaware one, Maryland six, Virginia ten, North Carolina five, South Carolina five, and Georgia three.
