Should I write my master's thesis in English, as a non-native speaker? I'm currently enrolled in a Master's degree Program in Statistics in Italy. I just started working on my thesis and my advisor asked me if I wanted to write it in Italian or in English. Apparently, both languages are accepted but presenting a thesis in English would mean having to discuss it in English too.
It's a 10-min Q&amp;A session so not that big a deal, however I wouldn't want to put the evaluating committee in a difficult position since none of my professors are native English speakers.

Given that I have no interest (at the moment) in pursuing an academic career beyond my Master, what could be the benefits of writing the thesis in English? Would it realistically make any difference for future job search abroad, for example?
The reasons I write all my work in English, regardless of the country in which I work, are threefold: 


The scientific community works in English
English texts are easier to reuse
English texts are easier to share and diffuse


Reasons 2 and 3 are effectively based on premise number 1. In terms of the ability to reuse my work, more often than never I might have to give a presentation, a talk or create a poster based on some report/thesis/paper I previously wrote. This scenario is  common to both academia and industry. When this happens I can easily extract sentences, keywords and figures from my previous work if all the text contained in them is in English, without the need to translate it.

Similarly a document written in English can be given to anyone and they'll be able to read and understand it without requiring a translation. 

Therefore if I were you I would write the thesis in English, and present it also in English. I don't think that your examiners will feel in any way threatened by this. Ever more so if you are a foreign student and Italian is not your native language. You should not be expected or forced to write and/or present in a language you are not that familiar with, if English is an allowed option.
