Recommendation Letters-Applying for transfer

I'm in my first semester of college, and I want to apply for a transfer to the one I actually planned to apply for (I hadnt before). Right now, applications have opened for fall 2026.

When is a good time to ask university professors for recommendation letters? It's been only a month so far studying with them, so I want to give it more time for them to get to know me properly. How do you even ask your current professors for LORs and tell them you want to transfer to another university 😭

Please help. I need at least 3. Application deadline is end of jan.
