Invitations are how you make connections on LinkedIn. When one LinkedIn member sends an invitation to another person who then accepts the invitation, they become 1st-degree connections. If the person receiving the invitation isn't a LinkedIn member, they'll be prompted to join LinkedIn in order to accept the invitation. Each new connection can increase your access to thousands of professionals in your network.

**Notes**:

-
To ensure an optimal site experience, LinkedIn members can have a maximum of 30,000 1st-degree connections. Learn more about LinkedIn’s network size limit.
