The Citizenship and Immigration Service (USCIS) can reject requests for immigration procedures if it finds an error in the corresponding forms, so it is necessary to avoid making mistakes and not repeat the process again.
When carrying out a procedure with the USCIS, it is important to complete the corresponding form by filling in all the boxes and not leaving blank spaces. Also, it is necessary to verify that the form is signed.
Another recurring error in filling out forms is not using the most up-to-date version of it. It is recommended that all forms be obtained from the official USCIS website: https://www.uscis.gov/es/formularios/todos-los-formularios
All forms must be completed using black ink, handwritten as legibly as possible. Try to use all the space provided by the boxes on the form. If you make a mistake in filling it out, it is necessary to start from scratch and print a new form, since the use of corrector, markers, among others, affects their reading by the USCIS, since they use special scanners to read them.
Once the form is completed, the next step is to pay the corresponding fee. Enter the USCIS fee calculator at the following link: https://www.uscis.gov/feecalculator. If the wrong amount is paid, USCIS will reject the petition.
The next step is the shipment, the package must contain the check or money order with the corresponding fee, the notification forms, the form with the request of the interested party and supporting documents.
Easy-to-open envelopes or folders are recommended, unless USCIS requires otherwise. Don't use staples. On the envelope you should write the reason for sending and the number of the form you filled out, for example, I-539.
Finally, check that the shipping address is correct. Check the shipping addresses directly on the USCIS site: https://www.uscis.gov/forms/forms.
