FAANG companies are good options for foreign engineers because they have a very organized application -> visa -> green card pipeline. If you're interviewing at a small startup, it's very hit or miss whether their legal team will be willing and competent enough to get you into the country safely.

I'd actually recommend small startups for most people, given growth opportunities, but if your primary concern is to get into the US on a permanent basis, it's much safer to apply to a large boring enterprise with a good legal team.
