Welcome back to the Wefugees Community and thank you for reaching out to us again.
Unfortunately, it is hardly possible to predict the outcome of an asylum procedure or to make any serious assumption here - especially without knowing your fiance's background and story. Every asylum application is getting assessed individually by the Federal Office for Migration and Refugees (BAMF).
Was your fiance interviewed already? In case he is still waiting for the interview ("Anhörung"), I can only recommend to prepare this appointment as most important part of the whole process very well. There are counselling offices which are specialised in supporting and preparing applicants for the interview - it is the so-called "Asylverfahrensberatung".
Please let us know if you need help in finding such an office close to your fiance's location.
All the best,
