Thanks to everyone for the tips!!! I tell you what I did.
Compressing was not working because it is a total of 35 scans.
The process I was doing and was not working was: scan with Notes-convert into PDF-merge PDFs (adding a cover google docs explaining what is in the PDF) and then it was 17 MB. š
Impossible to compress.
SO: I did this: take every single PDF scan and convert into JPG. Then reduce the size of each single jpg to 900px width- then take them all and convert into PDF again. Then merge into a pdf then compress it.

And it is 3MB.
All with ilovepdf.
You have no idea of the level of stress haha.
Thanks again to you all. Will keep u updated with my visa resolution and process!
