I don't understand the dismissive comments being made here, is it that hard to believe that there could be a problem with the current immigration policy?
You don't understand because you have no idea what you're observing. Nobody believes that there are no problems with any immigration policy in Sweden (as there have been several changes since 2014). You can drop that bit.
In 2016 there was a majority decition to apply a temporary law for immigration, limiting some groups from entering the country. Majority in this case means support from most parties left and right, 75% of representatives voted "yes". So,
most people (by representation) have
some problem with the immigration policy. If that sounds insanely reductive that's because it is, but at least it's not as reductive and false as no problem, which is silly within any context, as there will always be room for improvement, and in a working democracy it's all about making compromises.
Depending on the individual situation for each and every person that comes here, you may be classified as one of three categories of migrants. One of those categories is refugee. If you are a refugee, you cannot be deported, as that breaks national law, EU law, and UN conventions. Unless you know the specifics of each categorization, you should never call for a ban on immigrants. You should also refrain from giving your valuable opinion, because it probably doesn't mean shit.
One of the main reasons for limiting immigration is that the Swedish Migration Office was not able to handle application within a reasonable timeframe. At its peak you'd have to wait 1.5 years for a decision as to wether or not you'd get to stay, which is pretty unreasonable. The temporary law limits new applications coming in and the Migration Office is working to get through applications.
This limit would be hard to foresee as the increase in numbers meant a lot of new recruits (more jobs!) at the Migration Office. These inexperienced officers take as long as 3x the time, if not more, to work through one application. During this time, the Migration Office has gone through a chock-like reaction to the number of applicants which has spawned a notable number of changes for an otherwise slow beurocratic system. Had the service been better prepared, the current situation could've looked very different.
So there are a multitude of factors playing into this, and there are a lot of complex issues. If you're referring to YouTube-videos as your source you're out of the loop, guaranteed.
And those wanting to completely stop refugees from seeking asylum are calling for illegal actions. That right there is a clear warning that a person 1) has no clue and 2) doesn't care enough to get a clue and 3) is probably a anti-feminist racist alt-right douchebag.
