Hi Shadi,
I´m not sure if there is anyone in our communtiy yet from Mönchengladbach, but there is a Facebook group that posts events in Mönchengladbach where you could meet people!
https://***.facebook.***/ASYLinMG/timeline
I don´t see any events coming up that are hosted by the organization, but there is this event:
https://***.facebook.***/events/1165996603432934/
I would visit their office and see if there are discounted tickets to the event, and ask for other advice about making friends in Mönchengladbach!
Address: Waisenhauststr. 22
All the best :)
Julia
