^ first post is excellent advice. You need to think about where you're getting your information and who benefits from the information you're getting. Tabloids like the daily fail are very keen to scapegoat asylum seekers and other minority groups in order to divert the publics attention away from who is really at fault for our economic issues, housing and social care issues. It's not asylum seekers btw.
Having worked extensively with asylum seekers, yes people do often give each other advice and it can be very problematic but more so because a lot of times the advice is well intentioned but incorrect and can actually destroy a claim for asylum. Often people are totally genuine but just desperate and scared and want to make sure they are approved because the alternative could kill them. Its not that they're fake or disingenuous.
You wonder why it's mainly males who make the journey but think about what the journey entails and how often fatalities occur. Nearly all (and when i say that i mean 99%) of the people I've worked with have been SA or trapped into forced labour at some point on their journey. The majority of the accommodation in other countries is vastly unsuitable and unsafe and illegal pushbacks happen constantly in other countries. Plus the refusal by some countries to intervene and rescue people who are drowning that they could help. When you think of that, is it any wonder that men are seen as the better candidate for the journey with the hope their female or younger/older family members could follow in a safe way?
The idea that ANYONE is putting themselves through such trauma and risking their life on one of those boats just for the craic or to get one over on us by claiming benefits or to just come to cause trouble is actually ridiculous.
I'd say there are difficulties with cultural integration, but responsibility for that exists on both sides and often people are pigeon holed into segregated communities, experience racist abuse, become more isolated and are therefore more susceptible to radicalisation either online or by people who have been here since birth. Most people leave their countries because they are escaping extremist regimes in the first instance. Expecting someone to come to a new country and abandon their language/ religion/ culture/diet etc because "well this is England " is highly racist and shows a lot of ignorance and that type of thing happens all the time.
Our home office process is incredibly hostile, overly lengthy and not fit for purpose. Often people's mental health takes a significant dip while waiting years for any sort of progress on an application. During that time people can't work to support themselves/ use skills they've trained for/volunteer with certain types of organisations and claim a lesser amount than people on a flat rate of UC get.
