Who goes to a Jewish wedding?

Answer 1

If the wedding ceremony is in a public place, like a synagogue or a social hall,

then anybody acquainted with or in the community of the bride or groom or their

families may attend to express their support and good wishes for the couple.

Certainly, nobody would be refused admittance to the ceremony.

Concerning the celebratory events following the ceremony, such as a reception,

dinner, party, or events during the seven days following the wedding, anybody

invited by the couple or their families attends those. That could include friends,

relatives, classmates, co-workers, business associates, etc. A lot like wedding

events in any other community, I would imagine.
