EJSE welcomes manuscripts from researchers in all countries. The acceptance rate is about 20%. Review is double blind.
For editors and reviewers to accurately assess the work presented in your manuscript you need to ensure the English language is of enough quality to be understood.
If you need help with writing in English, you should consider:
1) Asking a colleague who is a native English speaker to review your manuscript for clarity.
2) Using a professional language editing service where editors will improve the English to ensure that your meaning is clear and identify problems that require your review.
