Fiancé arriving on K1 Visa to SFO can I meet her at the gates?

Hi all. My fiance had her K1 Visa approved. She is flying into SFO via Singapore Air. I am meeting her at the airport, but I would like to meet her at the Gate as she arrives. Would that be allowed? I believe its teminal 1. It's her first time in the US. I wanted to go with her as she goes through immigration. I just want the process to go as smooth as possible.
