The United States Congress stands as the legislative bedrock of the American federal government, a powerful and pivotal institution designed to represent the will of the people and the individual states. It embodies a bicameral structure, meaning it is composed of two distinct legislative chambers: the House of Representatives, often referred to as the lower body, and the Senate, known as the upper body. This dual-chamber design, a result of compromises during the nation's founding, ensures a system of checks and balances while addressing concerns of both population-based and state-based representation.

All congressional proceedings unfold within the iconic United States Capitol building, a symbol of American democracy nestled in the heart of Washington, D.C. Both senators and representatives are chosen through a process of direct election by the citizenry, a significant evolution from earlier methods of selection, particularly for senators who were once chosen by state legislatures. However, should a vacancy arise in the Senate before a scheduled election, it may be expediently filled by an appointment from the state's governor, ensuring continuous representation.

In total, Congress comprises 535 voting members. This includes 100 senators, with each of the 50 states receiving two representatives regardless of its population size, affirming the principle of state equality in the upper chamber. The remaining 435 voting members constitute the House of Representatives, where representation is directly proportional to each state's population. Interestingly, the Vice President of the United States serves as the President of the Senate and holds the crucial power to cast a tie-breaking vote, but only when senators are evenly divided on a particular matter. Beyond these voting members, the House of Representatives also includes six non-voting delegates and resident commissioners representing various U.S. territories and the District of Columbia, who advocate for their constituents' interests though without the power to vote on legislation.

A typical sitting of a Congress spans a two-year term, commencing every other January. The rhythm of American democracy dictates that general elections for federal offices are held consistently every even-numbered year, specifically on the first Tuesday after the first Monday in November, widely known as Election Day. All members of the House of Representatives are elected for these two-year terms, ensuring they remain closely accountable to their constituents and are frequently subject to review by the electorate.

The apportionment of representatives within the House is a dynamic process governed by the Reapportionment Act of 1929. This legislation mandates that House members are elected from single-member constituencies, commonly known as districts, using the "first-past-the-post" system, where the candidate with the most votes wins, even if they don't secure an absolute majority. Crucially, these Congressional districts are redrawn and allocated to states every ten years based on the results of the United States Census, reflecting population shifts across the nation. A fundamental guarantee of this system is that every state is entitled to at least one Congressional representative, regardless of how small its population might be.

Senators, on the other hand, serve longer six-year terms, elected "at-large" across their entire state. To ensure continuity and stability within the Senate, their terms are staggered, meaning that approximately one-third of the Senate seats are up for election every two years. This deliberate design prevents a complete turnover of the chamber at any single election cycle, fostering institutional memory and legislative expertise. The principle of equal state representation, regardless of population or geographical size, is steadfast in the Senate, which is why currently there are 100 senators representing the 50 states.

Qualifications for Congressional Service

To serve in this august body, specific criteria must be met, as outlined in Article One of the United States Constitution. For aspiring members of the House of Representatives, the Constitution requires them to be at least 25 years old, have been a citizen of the United States for a minimum of seven years, and be an inhabitant of the state they represent at the time of their election. For the more deliberative Senate, the age requirement is slightly higher at 30 years, coupled with a longer nine-year U.S. citizenship prerequisite, and likewise, they must be an inhabitant of the state from which they are elected. A testament to the open nature of American politics, members in both chambers are permitted to stand for re-election an unlimited number of times, allowing for long and distinguished careers in public service.

Historical Context and Political Affiliation

The Congress was born from the foundational debates of the United States Constitution and first convened in 1789, marking a significant transition from its predecessor, the Congress of the Confederation, which operated under the Articles of Confederation. While the Constitution does not legally mandate political party affiliation for its members, a powerful and enduring tradition has emerged since the 19th century: Congress members are almost universally affiliated with one of the two dominant major parties, the Democratic Party or the Republican Party. It is indeed a rare occurrence to find members associated with a third party or serving as independents without formal party ties.

However, the absence of a formal party affiliation does not necessarily preclude such independent members from participating in the legislative process effectively. They often "caucus" or align themselves with members of one of the major political parties, pooling resources and influence on specific issues. While not common, members retain the freedom to switch their party affiliation at any time, a choice that can sometimes carry significant political repercussions.

The Chinese Exclusion Act: A Landmark of Restriction

In a dark chapter of United States immigration history, the Chinese Exclusion Act was signed into federal law by President Chester A. Arthur on May 6, 1882. This unprecedented legislation explicitly prohibited the immigration of all Chinese laborers to the United States. Its passage represented a culmination of decades of growing anti-Chinese sentiment and violence, particularly on the West Coast, where Chinese immigrants had played a crucial role in developing industries like mining and railroad construction but faced intense xenophobia and economic competition. This act did not emerge in a vacuum; it built upon the foundation of the earlier Page Act of 1875, which had already placed severe restrictions on the immigration of Chinese women, primarily under the pretext of preventing prostitution, but effectively limiting Chinese family formation in America.

What made the Chinese Exclusion Act singularly notorious was its distinction as the only law ever implemented in U.S. history to prevent all members of a specific ethnic or national group from immigrating to the United States. It was a stark departure from the nation's purported ideals of welcome and opportunity. The journey to its enactment was paved with escalating anti-Chinese sentiment, manifested in widespread anti-Chinese violence, discriminatory policies, and targeted legislation aimed squarely at Chinese migrants. Prior to the act, diplomatic efforts also paved the way: the Angell Treaty of 1880, a set of revisions to the existing U.S.-China Burlingame Treaty of 1868, notably granted the U.S. the right to suspend Chinese immigration, thereby laying the legal groundwork for the exclusion policy.

Initially, the act was intended to be a temporary measure, set to last for just ten years. However, the political will for exclusion proved tenacious. It was renewed and even strengthened in 1892 with the passage of the Geary Act, which, among other things, required Chinese residents to carry certificates of residency, essentially identity papers, or face deportation. By 1902, the policy of exclusion was made permanent, cementing a discriminatory stance that would endure for decades. These laws aimed to halt almost all Chinese immigration, though they did provide limited exceptions for specific classes of individuals such as diplomats, teachers, students, merchants, and travelers, underscoring the racial and class-based nature of the prohibition. Despite the stringent measures, the laws were widely evaded, with many Chinese immigrants resorting to clandestine entry methods, highlighting both the desperation to enter and the inherent flaws in enforcing such a broad prohibition.

The Chinese Exclusion Act, and its subsequent renewals, remained in force for an astonishing 61 years, casting a long shadow over U.S. immigration policy and U.S.-China relations. Its repeal finally came with the passage of the Magnuson Act in 1943. This repeal was largely influenced by the geopolitical realities of World War II, as China had become a vital ally against Japan, and the continued exclusion of Chinese immigrants was a source of international embarrassment. While repealing the outright exclusion, the Magnuson Act was still highly restrictive, allowing only a modest quota of 105 Chinese immigrants to enter the United States each year.

Significant liberalization of Chinese immigration, and indeed broader U.S. immigration policy, occurred with the passage of the Immigration and Nationality Act of 1952, which abolished direct racial barriers in naturalization, and even more profoundly, by the Immigration and Nationality Act of 1965. The 1965 Act dramatically reshaped U.S. immigration policy by abolishing the discriminatory National Origins Formula, a system that had favored immigrants from Western European countries, thereby opening the doors to increased immigration from Asia and other parts of the world.
