Applying for permanent residence in the United States can be a complicated and lengthy process. The last thing you want to hear after going through the process is that your application has been denied. If you applied for a green card and weren't approved, there are still steps you can take. Here are four things you should do if your permanent residence application is denied.

1. Hire a lawyer.

The first thing you should do once you get the rejection is to hire a lawyer. There are many reasons your application could have been denied, and you'll want a lawyer to walk you through the process of figuring out how to correct whatever went wrong. Time is of the essence, so don't wait to look for an experienced immigration attorney.

2. Appeal the decision.

If your lawyer thinks your green card application was denied due to an error on the immigration court's end, they can help you appeal the decision. According to All Law, the appeal must be made within 30 days of the original decision. Your lawyer may need your input, but they will handle all the paperwork necessary for the appeal. You will, unfortunately, have to pay a fee of $630, and reversals of immigration court rulings can be hard to obtain.

3. Reapply.

If your lawyer thinks it is not in your best to appeal the immigration court's decision or if your appeal was denied, the next step is for you to reapply for permanent residence. Let your immigration attorney fill out the necessary forms and documents, since their expertise will ensure there are no errors on the paperwork. Having your application completed by a lawyer is your best chance to secure a green card.

4. Attend all court dates.

If you're scheduled to appear in court, it's very important that you attend promptly. Missing a court date could mean that your whole application is thrown out, in which case you won't be eligible for permanent residence. You may even be immediately deported or face other disciplinary actions. It's in your best interest to comply with all requests from the court and judge overseeing your hearing.

Being denied a green card doesn't mean you have to immediately leave the United States. Remain calm and consult with an immigration attorney who can explain all your options. These steps will get you started in the process to secure your permanent residence.
