If you are not a US citizen and you are thinking about coming here, please strongly reconsider. I would be concerned for your safety, and to be honest these idiots need to feel the pain of tourism and international business drying up.
The US has what are effectively secret police snatching up people and disappearing them into a detention system. Some people reemerge in two weeks, some stay in there.
Don't risk it until something changes.
Security and hacker conferences and the like should really be considering alternate venues for international audiences, and consider whether they are being held in places queer folks within the US can safely attend.
