Will I go back to HK in Feb?

2 days ago, I suddenly received a phone call for an interview of a student job. Not without difficulties, we arranged an interview today. It is about a stupid technical support kind of job in Akzo Nobel. They had an advertisement at my faculty. I tried everything I could which are posted on the notice board... :p I asked them to send me an email: "wie mit Ihnen soeben telefonisch besprochen, laden wir Sie zu einem Vorstellungsgespräch am Mittwoch, den 11. Januar um 14 Uhr zu uns ein. *Wir bitten Sie uns eine gültige Arbeitserlaubnis mitzubringen*. Unsere Adresse können Sie unten ersehen." The most important point to work abroad to me is not qualifications, but a "working permit" :p Today I had the interview. The interviewers were very nice. They asked me if I like a drink, a cake, a cigarette etc. I think they must be very desparate in hiring a student helper, so they also consider an exchange student. :p If they are going to hire me, will I go back to HK in Feb? Headache...
