Our app does not allow you to withdraw Forms I-864 or I-134 as these are not normally withdrawn by the USCIS. USCIS allows you to withdraw any pending applications that have not reached a result. Example: If you submitted Form I-864 with a Green card sponsorship application with Form I-130, then you can withdraw it and I-864 will also be automatically withdrawn. Similarly, if your submitted Form I-134 with a B1/B2 visa application for your parents or relatives, then you can withdraw that B1/B2 application and get rid of Form I-134 too at the same time.
