Post Decision Activity is something that happens after the USCIS adjudicates a petition. USCIS is the federal agency that takes care of issues related to immigration. To receive immigration benefits, appropriate USCIS forms must be filed and the USCIS will adjudicate the petitions after checking the petitions. USCIS must first accept the petition that you file and this is the first step and the USCIS will not accept petitions that are incomplete and inaccurate. Similarly, your petition will not be accepted if your signature is missing. It is hence mandatory to make sure that your form is signed and that the form is completely filled. Likewise, if you have not have signed in black ink, your petition will be rejected.
Moreover, you need to check your application package prior to mailing and make sure that the package contains the required form filing fee. Some people mail copies of completed immigration forms instead of filing the original copies and such copies will not be accepted and will immediately be rejected by the USCIS.
After checking your petition for accuracy and after ensuring that you have paid the right fee, USCIS will accept your petition and remember that acceptance does not mean approval. USCIS will check whether you have completed all the fields of the form and whether all the supporting documents are submitted. USCIS will then send you an application receipt notice. Your petition will be rejected immediately, if it does not accompany all the relevant supporting documents and the form filing fee. Similarly, if your petition is incomplete, your petition will be returned to you.
Hence, all the essential documents must be submitted without fail, in order to prevent your petition from being denied. If the supporting documents are insufficient and if the USCIS does not deny your petition for this reason, it will request you for more evidence. As soon as you receive such a request from the USCIS, you will have to mail all the relevant documents to the right USCIS address. In certain circumstances, you will be required to submit original documents.
If an interview is required, USCIS will send you an interview appointment letter and an interview will take place after the agency reviews your petition and the supporting documents and the USCIS will decide on your case, after the interview.
Post decision activity will include all the actions that the USCIS takes after denying or approving your petition. If your petition is approved, USCIS will send a notification to the US Department of State or to the National Visa Center and this is known as post decision activity. If your petition is denied by the USCIS, you can appeal the denial of your petition and if your request is considered, USCIS will reconsider your case. All these activities are regarded as post decision activities. Post decision activities involve several steps and you may check the steps online, by making use of your case number.
