@aram conferences generally really must relocate. The USA is simply not safe, and people can be barred on a whim. At the very least a substantial online stream should be offered. It's really problematic given how crucial some conferences are for networking and sharing.
Suggestion: offer a parallel European location, with a live stream.

Come to Canada. For the moment at least we'll even allow people with a US[LN]A passport to enter (and even leave!) without imprisonment.

@alan @artemis @aram The feasibility of relocating to Canada may depend on the size of the conference: some years ago I attended some standards meetings and they always seemed to be held in the wrong season. The reason was that there aren't that many venues that can hold a very large group so you have to get the venue several years in advance.
At least that's the reason they gave us.
