If I'm reading a piece by an author whose 1st language is not English, I'll make adjustments in what I think mistakes say about them. Most readers will. And I'll be focusing on content and ideas and glossing over sentence details.
It can be even be a positive, "This is impressive writing for a non-native speaker..."
If, on the other hand, you are trying to pass yourself off as someone with the same command as a native speaker, I'll be turned off.
