What are the consequences of submitting Form I-924A late?
What will happen if USCIS does not receive a regional center's Form I-925A by December 31? Can the regional center continue to operate even if the Supplement is received late?
It is advisable to always file timely. If filing late then valid reasons should be submitted with the late filing,then the USCIS has discretion as to whether to accept the late filing.
