As the U.S. Senate attempts to push an immigration bill, I can’t help but note that America remains the land of opportunity for so many.

After more than 230 years, why do immigrants still come to America’s shores? Why is America still considered a land of utopia?

Because it is here where one works towards accomplishing the American dream — an opportunity for advancement and prosperity.

Here, hard work opens doors and provides opportunities. Though college graduation is advised, it is not required. The list of people who have succeeded without its benefit is long. It includes presidents Abraham Lincoln and Andrew Jackson; entrepreneurs, Ray Kroc (McDonald’s) Colonel Harland Sanders (KFC) and Dave Thomas (Wendy’s); photographers Gordon Parks and Ansel Adams; architect Frank Lloyd Wright; Henry Ford; and computer developers Steve Wozniak and Bill Gates.

To those who pursued education, America has allowed them to better their lives. Look no further than America’s last three presidents and their spouses, Barack and Michelle Obama, George and Laura Bush, and Bill and Hillary Clinton.

Where else would these men have become president?

Where else could seeking the presidency, if desired, even be a consideration for their wives?

Writers who have attained continued commercial success include Suzanne Collins of “The Hunger Games,” John Grisham (“A Time to Kill,” “The Firm,” and “The Client” and Tom Clancy, author of “The Hunt for Red October” and “Patriot Games.”

America offers the chance to pursue happiness as stated in the Declaration of Independence.

“Give me your tired, your poor, your huddled masses yearning to breathe free,” is part of the inscription on the Statue of Liberty. America is that inscription in action.

Everyone who calls this country home, inherits a potential for greatness, invokes the promise of forefathers to make this nation better.

We are a nation moving forward.

The Emancipation Proclamation and the Civil Rights Act of 1964 picked up where the Declaration of Independence faltered.

The Nineteenth Amendment, which established women suffrage, ended the disenfranchisement of women in the political process.

Today, others still clamor to come to America — for even the vaguest chance at prosperity, education and equality.

This Independence Day, though besieged by budget constraints and sequestration, America’s dream is no nightmare and must be cherished.
