Help with college/uni apps as international student

Hello from New Zealand! I am needing a bit of help because I have no idea what to do as an international student.

I am a year 13 student [which is final year] (I am doing NCEA level 3 in 2025) and I am going to apply for USA Universities as international student. I want to study medicine. For USA is there any undergrad/premed course I need to do or am I able to straight away go into medicine? I am a bit unfamiliar and need help with the timeline of when/how to apply. I got my level 2 exam results (got excellence endorsed woohoo!) and I am planning to sit the UCAT exam this year.

My questions are:

1) When & Where do I apply for USA universities to study medicine?

2) When, where and how do I apply for scholarships for mediciċe?

I would appreciate any help and guidance for this issue I am facing :)
