Will I lose college credits after so many years if graduate?

No, you won't lose college credits *after* you graduate. Once you've earned a degree, those credits are yours permanently and are recorded on your official transcript.

However, if you haven't graduated and haven't attended college for a significant period (usually several years, the exact timeframe varies by institution), your credits might become inactive or expire. This means you may need to contact the institution to reinstate them before you can continue your studies there. This isn't a loss of the credits themselves, but rather a loss of their *active* status.
