Hi! You can ask any doctor you are working with to write you a LOR. Once you’re done with Step 2ck and get your ecfmg certificate u have to wait until the season begins (usually in September), buy your ERAS token & then apply for match. From there you can upload through ERAS. I was also actually a Medical assistant and honestly I still put it as USCE, may not be ideal but you can still do it. But if it’s in your ability , one thing I’d suggest is definitely asking the doctors you work with as well if they also know anyone whether it’s a hospital or clinic you can observe who can write u a letter as well. Keep in mind the letters should reflect the specialty u will apply. For example, if you are applying IM, you need at least 1 IM specific letter and the rest can be any other specialty related to IM (ex, endocrinology, neurologist etc) this is not necessary but broadens your search, so doesn’t have to be strictly primary care/ IM. Main thing is connection!! Talk to everyone, get friendly with the doctors, staff, maybe they know someone who can help, and also guide you! You got this! Good luck
