I think the time should rather be high to protect the integrity and purpose of the refugee system both to protect it from the harmful image of just another way of migration and to ensure it is not used as such. Another way is to make the refugee system more strict as for who counts as a refugee and being more lenient about working for those accepted, which would also be okay solution, but it still harms the actual function of the system imo. Integration is absolutely an important goal for those who end up staying, but there's other ways of doing that than just work, which is prone to abuse. And in the end it's something that has to be balanced with all of the goals. That's why I think working should be a rather exception for those who have been in the destination country for a long time without a clear path for returning than a rule.
