Because of the U.S. Government shutdown the U.S. Copyright Office is also closed. Still they are accepting submissions of works through the digital channel we are using to send works for registration, so ve encourage you to keep on sending your works to through Safe Creative’s system as the U.S. Copyright Office confirms it will respect the date and hour of presentation. Anyhow, the resolution of the case may delay some additional time depending of the lasting of this shutdown.
Remember that to uso this service you have to have a Safe Creative’s Professional Account.
