Calling all International brides!! civil marriage+ symbolic wedding or vow renewal

You can call it whatever you want. If in your culture, you would have called it a wedding on the invitation, do so. I'm assuming since having separate civil and religious ceremonies is the norm in your culture, then just invite your family/friends/guests to your wedding and call it such since that's the norm for your family/friends.

Don't worry so much about American customs. Having multiple weddings is very common for grooms/brides whose family/friends are very far apart, especially if you're an immigrant or have immigrant parents. My cousin threw 3 separate wedding ceremonies + receptions in Korea, China, then back to San Francisco for their US based friends and family. Everyone knew they were having 3 weddings in order to properly host family and friends who lived in different parts of the world. We were all still happy to witness them making vows to each other and party afterwards. I just came back from another another wedding in Austin, Texas, for an old school friends and they are flying to their Australia wedding next week for her side of the family. My brother in law is having his Argentina wedding this June, and then they're coming back in July to do it again for his family and friends. I will happily attend their second wedding and reception.

Your friends and family love you and just want to celebrate your marriage with you. They're not going to care what you call it, but for reference my friends have always called it a wedding regardless if they were doing multiple ceremonies. It's just a cultural preference, not something "deceitful."
