Unfortunately, USCIS does not allow you to pay the green card application fees in installments—you must pay the required fees in full when you submit your forms. This includes the filing fee for Form I-130 and, if applying from within the U.S., Form I-485 and the biometrics fee. If these fees are difficult to manage upfront, consider saving gradually or exploring options like personal loans to cover the costs.
If hiring an attorney, many law firms offer flexible payment plans for their services, allowing you to spread out the cost of legal assistance while ensuring your application is completed properly. It’s important to plan ahead to cover these expenses since incomplete payment will result in delays.
