Ceiling by form
Citizenship guidance caps uploads at 5 MB while the general portal FAQ defaults to 20 MB unless a form states otherwise.
How we handle it: UploadPrep targets the 5 MB citizenship contract, which also passes any 20 MB form.
Filenames
Uploaded files cannot contain commas in their names.
How we handle it: Rename files without commas before upload.
