The thing is, you completely ignore that there are other families from different countries aside of those from South America that have applied for such. Not sure about asylum seekers but there is a quota for immigrant visas. That's one of the things that pushed the processing of our immigrant visa application to 10 years. Not to mention the processing for these can bounce from a different application year to another. At one point, Our application was around Oct 2007. We got called for an interview around 2009 IIRC. From that point, we were held off because of changes in the document requirements. We tried to accomplish them but the immigrant processing date changed to something in 2005. So what that means is that there are still others who have applied at an earlier date and have not been fully processed.
Now regarding the case of the march to the border that's currently happening. It's going to be a fucking nightmare for these guys. You can't expect to just get ahead of those who are already lined up. That's what the general public should know. It's not that easy to control it but you should NOT open the gates just because of that.
I mean Trump does love to exaggerate but let's say for example that there is a small percentage of asylum seekers who are allowed to go through who are actually troublemakers. It adds more risk to the citizens inside the country.
One of the best tragic examples of uncontrolled immigration is Sweden. They let a lot of people in. There were not enough proper program for the migrants to transition. They don't have enough jobs. They don't have proper housing. A lot of the migrants were out on the streets. I had a friend there who was mugged by a migrant. He had to move to a different place because of how dangerous his old town became. Now, with the tone of the democrats, they want to do the same thing. Just let people in without due process expecting a Hail Mary solution to get these migrants stable.
What you described is a prime example of a flaw within our immigration system. The process should simply never be that complicated or time consuming and while your experience sounds like something that doesn't happen to everyone the best case scenario can still take well over 6 months. That's my problem with the way republicans handle this, they claim to be pro legal immigration buey do nothing to fix the problems that already exist within the system and in some cases even make it worse. The Democrats share some blame considering that we didn't leave the Obama era with a flawless immigration system but the people in charge right now are too busy fear mongering to truly change how we do things
