I don't see a problem with this. The lingua franca is English. Prior to that it was Latin. In science you're held to a higher standard and this is a small issue. > Compared to a fellow PhD student who happens to be a native English speaker, you’ll need 91% more time to read a paper in English. This equates to an additional three weeks per year for reading the same number of papers. > The next big hurdle comes when trying to publish your own paper in English. > First, you’ll need 51% more time to write the paper. Then you’ll likely need someone to proofread your text, such as a professional editor. This is non-sense and is given without a single source other than a study likely tailor made for this result. I know plenty of ESL scientists and this is the least of their concern.
