Multiple member llc owner's pay

I’m working with a 2 member llc with no s-corp election. One owner is from Japan and not an American resident while the other is a DACA recipient with a valid social security number. They sale apparel on Amazon.

Would they just take a reasonable salary and what kind of taxes should they be saving/paying?

I’ve heard the Japanese owner would be classified as an international investor and the llc should be withholding 22% of his portion of the profits to turn into the IRS.

Would something like this also apply to the DACA recipient?

Also, if covered on a podcast can I get the podcast name and episode number or title?

Thank you.
