The cost for filing an Adjustment of Status application includes the filing fee for Form I-485, which is currently $1,140 for most applicants, and a biometric services fee of $85. Additional costs may be incurred for medical examinations, translation of documents, and legal fees if the applicant chooses to hire an attorney to assist with the process. Applicants should consult the latest fee schedule on the USCIS website or discuss with an immigration lawyer to understand all associated costs.
