Much easier to do when we're talking about a small country like Hungary. The US is way different and the sheer size of the proposed wall is staggering. Not impossible, but highly improbable.

If people wanna immigrate into a new country, there are legal means to do so and they should pursue it that way. Illegal immigration is a bane that serves no one except the immigrant.

If you can't get in legally, sucks to be you. Stay home then. Quit making your life someone else's issue.
