Call fro immigration to go to office with no explanation?

[Dnas17]

My girlfriends parents (entire family is refugees awaiting a hearing) recieved a call and were instructed to report to an immigration office on Friday with no explanation. They have recently been trying to apply for work permits but were denied due to improperly filling out the forms. Is this what they could be summoned to discuss or are they facing something more serious?

It's not a criminal act to pick up the phone and ask them the reason why the called!
