As an undergraduate, is it alright to get help finishing my paper?
For scholarly work, as opposed to classwork, it is fine to ask for help whether you are an undergraduate or a full professor.
However, the nature of the help needs to be considered. For simple editing and phrasing, an acknowledgement of the help within the eventual paper is probably enough. But if it crosses the line to the point where the &quot;helpers&quot; are contributing ideas, then they become collaborators and co-authors.
Some publishers will provide technical copy-editors if that is all you need, but I think this is more likely for books than papers. It might even be that most of the editing you need can be done by a general text-editor as long as you vet what they suggest. Sometimes they will get it wrong and you need to be able to see and correct that. But such services are likely more available than someone with experience in your field.
After submission, some reviewers will suggest rephrasing as needed. But there is no guarantee of it. Telling an editor of a journal that you need a bit of help with the language might be worth the effort, but, again, no guarantees.
And, no, having collaborators and co-authors doesn't degrade the work. Collaborations with the right people can enhance it. But if you originated the key ideas you want to assure that you get credit for that. In some fields it is being the &quot;first author&quot;. In others it is just a short paragraph describing contributions. But at such an early stage, any publication will help you along. There aren't a lot of people who achieve that.
