You shouldn't have a problem if you have a normal employer with a technical culture. Everywhere I've worked has had flexible working hours(within reason), so getting in between 9-10 shouldn't be a problem, and the culture in the US is such that getting a couple cups of coffee while you read email and the company IRC/Slack isn't really a problem in a decent working environment. If it takes you longer than 30-45 minutes to be productive though, or you have a long commute, maybe you should get more sleep :p
