Hello Padma,

If a green card application is denied, the first step is to review the denial notice carefully to understand the reasons. You can file an appeal or motion to reopen/reconsider with USCIS if you believe there was an error. Alternatively, you may reapply if the issue can be resolved or seek other immigration options, such as applying for a different visa category. Consulting with an immigration attorney is advisable to explore the best course of action. Hope this helps.
