I am currently researching some information about Gazans who manage to emigrate in order to improve this answer. During this process I have found what it seems to be an interesting article about Gazan community in Belgium and more precise about a Gazan woman running for Office there:
Leila Wafi, who hails from Khan Yunis in the Gaza Strip, is running for office in the Belgian Parliament.
Wafi currently leads the Palestinian Women Union in Belgium. She has stated that if elected, she will promote the “rights of Palestinian refugees” in Belgium and will defend them throughout Europe.
I am trying to double check this information, but I am finding very limited information and only for Israeli sites (e.g. Jewish Press).
Question: Is a Gazan woman running for Office in Belgium?
As a side note, but related, any information related to Gazan community size is also appreciated.
