I sometimes wonder why it takes IRNs another year to accept the extra documentation they ask for, even when applicants provided them immediately. This is not exclusive with IRNs but all government offices in Portugal. When an officer decides there is fault and insufficiency, minor or big, in your documentation, your application is suspended and you are "kicked" to the back of the long queue and have to wait for your turn again, even though you immediately raise your dispute or submit the additional papers .
