That's the Declaration of Independence, not the Constitution. Some parts of the Constitution apply to non-citizens, some parts don't. For example, the 14th Amendment makes a distinction on this point--note the use of "citizens" vs. "any person": No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
