What would be the consequences of open borders?

Open borders means that there is no country. This is ridiculous. The U.S. will cease to exist without borders.

Impossible, every country needs to know who is in it. If it were to happen the population would explode exponentially, with not having enough resources society would collapse. Look at Britain, the Netherlands, Sweden if you need examples.

There are very few people who are advocating for completely open borders like how you can just cross state to state with no checks. Very, very few. In fact, the claims that all Democrats want truly open borders has been refuted in fact checks.

In Sept 2016, Trump said Hillary was for open borders. Actually she supported recent immigration legislation that sought to heighten the country’s border security while installing a new system that finds people who have overstayed their visas and has them removed from the U.S.

Near the end of Obama's final term, his administration deported more than 2.5 million during his entire time in office. That seems to be the opposite of open borders.

In 2013, every Democrat in the Senate voted for the Gang of Eight immigration overhaul bill that would have provided $40 billion for border enforcement, including sending thousands more agents and building 700 miles of fencing. Seems the opposite of open borders.

Every Democrat in the House voted for a proposal to enhance technology used to monitor the border, and provide $110 million in grants annually for collaboration between local law enforcement and Border Patrol agents.

Alexandria Ocasio-Cortez, the woman who won in New York recently, denied in an interview that she is for open boarders. She has stated that we have to have a secure border and make sure people are documented.

Our immigration laws are broken - I think we can all agree on that. However, the US did have open borders at one time. "Legal" immigration meant something entirely different in 19th and early 20th centuries than it does now. We basically let almost anyone in with a few restrictions like a health exam and the 1882 Chinese Exclusion Act.

Undocumented population increased in the 1960s when the US restricted the number of visas from Mexico. 1977, work visas were capped at 20,000 which was not jiving with labor demand.

Let's realize the US government has sometimes created the conditions that cause people to need to flee their countries. Overthrowing governments during the Cold War, financing military forces that massacred civilians or economic policies that put Mexican farmers out of work by the millions resulted in mass migration from Latin America. Perhaps if our government would mind its own business sometimes then there wouldn't be these crises that cause people to flee.

There is a small minority among Democrats that want to abolish ICE but all said they would like to have many of ICE’s functions redistributed to other, existing government agencies. None has called for abandoning border enforcement. They have argued that building a wall along the border is ineffective and waste of resources and rejected hard line proposals to immigration. I haven't seen any of the majority of Democrats say they want "open borders" or to let "everyone" come in.
