An immigration interview can certainly be rescheduled. A request to reschedule however should be done as far in advance as possible. A call has to be made to the USCIS service number at 800-375-5283 but it is advisable to follow up with a written letter to the adjudicating office. That letter should reference/confirm the date and time of the call request and it should provide a brief recap as to the reason for the request. Make sure the letter is sent so you have a record of delivery.
The agency is anxious to maintain a safe environment given the pandemic and they will gladly accommodate a reschedule request if based on a medical concern. The written appointment notices stress the importance of maintaining safe health protocols.
Naturally, the more specific and the more compelling a reason is, the greater the likelihood it will be granted. If possible, evidence should be provided to support the request. If it's a medical reason, give a medical record. If the reason is a material change in one's circumstances, document the change. If it's a humanitarian request, offer supporting evidence.
If your underlying reason to reschedule is not one you can support with evidence, simply make a general request (“because it conflicts with scheduling commitments I already have in place, place….…”).
While there is no requirement USCIS reschedule simply because a request has been made, they should be responsive to a timely request submitted with legitimate grounds.
Because (1) it takes so long to get to the interview stage, and (2) the interview ideally culminates in the approval of an immigration benefit, it is understandable that requesting a reschedule without an apparent need, can look sketchy. Even so, simply as a courtesy, they may schedule a new appointment.
