(Advice) Finishing up fieldwork season as a visiting student, considering asking if I can stay on as a RA in the Fall.

Title says it all basically. I’ve been working in the field collecting specimens, survey data, and helping out with other projects. I would love to commute up there 3-4 few days per week to engage in lab work, testing the specimens we’ve collected for various pathogens.

I am being paid for my role in the fieldwork and would also hope to be paid during the fall and beyond, is this common? Am I in the right position to ask?
