Considering a Move to Lisbon, Portugal

My partner and I are looking into moving from Beirut, Lebanon to Lisbon in spring of Protected content .

Any advice on how hard the move will be in terms of learning the language? We are fluent in english and arabic, and are only slightly conversational in french.

From what I've seen, you need to be fluent in order to hold any kind of job.

Any helpful advise will be appreciated.
