As the name suggests, a Conditional Green Card provides conditional permanent resident status. This Conditional Green Card is issued to people who get Green Card through marriage and also to entrepreneurs who apply for Green Card through investment.
This Conditional Green Card is provided instead of a Permanent Green Card because people have arguably abused this system in the past. People would marry a U.S. citizen solely to get a Green Card. To curb this misuse the government started issuing Conditional Green Cards.
The conditional Green Card is valid for 2 years and before it expires the couple should prove that the marriage is legitimate by filing a petition to remove the conditions on residence and follow through the next steps. The petition should be filed within 90 days before the card expires.
Failing to remove conditions on residence will strip the person of the residency status.
If you are a Conditional Green Card holder who acquired the card through marriage and looking to apply for a permanent one, then you need to remove the conditions on the Green Card by filing Form I-751 with the USCIS.

Conditional Green Cards are also issued to entrepreneurs through investment. The U.S. immigration laws allow people to get a Green Card through investment. The Green Card obtained through this method initially is a conditional Green Card similar to a marriage-based Green Card.
If you got your Green Card through investment, then you might need to remove the conditions on the Green Card by filing Form I-829 with the USCIS.

By law, it is required to carry the Green Card at all times. Because of this, you might lose or damage it, or the card could be stolen. If this happens then you need to apply for a Green Card replacement.
