Nah, you can bring your sponsor or not. Your choice. I landed by myself as it was an overnight trip to the consulate general and back, and my wife had to work.
Don't be nervous, Desdemona! Just relax. The application process is the hard thing. The landing is, as long as nothing has changed and nothing was withheld during the application process, just a formality.

I was just wondering if my sponsor must be present when I do my landing. I feel so nervous about the landing process.....it's the last hurdle in a very long journey.
