I should add here, if asked by immigration authorities at any entry point, you shouldn’t say you are there to travel AND work remotely. You are technically not allowed to work when on a tourist visa. But it is not possible for them to prove you did any work, esp when you are a remote worker.
You should also check your US tax and residency requirements. US has a tax exemption provision if you are not living there 330 out of 365 days. It has many caveats though.
