FILIPINO CREW MEMBERS: It is my first time applying for a US C1D visa, and I received a notification stating that an appointment has been secured for me but that I do not need a visa appearance. Should I be concerned about it?
Since if is your first time applying for a US C1D visa, you are required to attend the appointment in person. We will help you create a case with our visa team so they can assist you.  
We greatly appreciate your feedback.
