Based on your friend's issue with not seeing all their GitHub repositories when trying to import to Vercel, this is typically due to insufficient GitHub permissions. Here's how to resolve it:

Check GitHub App Permissions

The most common cause is that the Vercel GitHub App doesn't have access to all repositories 1. Your friend should:

1. During Import: When creating a new project, search for the missing repository and click "Import". If it doesn't appear, click "Configure GitHub App"
2. Direct Configuration: Go to GitHub Profile > Settings > Applications > Authorized GitHub Apps > Vercel and ensure the missing repositories have access granted

Other Permission Issues to Check

If the repository still doesn't appear after configuring the GitHub App, check these additional permissions 1:

• Repository Permissions: Ensure your friend has the necessary access to the repository
• Organization Permissions: If it's an organization repository, check that the organization allows third-party access
• User Permissions: Verify that your friend's GitHub account has proper permissions for the repository

Quick Fix Steps

1. Go to the Vercel dashboard
2. Try to import the project again
3. If the repository is missing, click "Configure GitHub App"
4. Grant access to the missing repositories
5. Return to Vercel and try importing again

This should resolve the issue and make all repositories visible for import to Vercel.
