Premium processing is an expedited review option offered by USCIS. It guarantees that USCIS will issue a decision on your petition within 15 business days.This decision is not an automatic approval. USCIS may approve the I-129 petition, issue a Request for Evidence (RFE), or deny the case. An approval at this stage only means the petition is approved; you would still need to attend a visa interview at a U.S. consulate in your home country, if applicable.One important consideration is that premium processing is not always the best choice. It effectively asks an officer to review a very large petition—often hundreds of pages—within a short timeframe, which can increase the likelihood of an RFE and ultimately prolong the overall process.Legal counsel will typically advise whether premium processing makes sense for your case, based on the overall strength and readiness of your petition once it is fully assembled.
