COS Application Review Service
Important:
USCIS recommends filing Form I-539 at least 45 days before your current status expires or as soon as you determine the need to change or extend status. Preparing documents may take several weeks, so please begin early.
This service is limited to checking whether your documents are complete and properly prepared for mailing to USCIS. POLY does not submit your application to USCIS and does not provide legal advice.
Before completing this form, you must complete the Application for Admission and Required Docs for Admission.
All uploaded documents must be in PDF format. Letters may be in PDF, RTF, DOC, or DOCX format. To upload multiple files, hold Ctrl (Windows) or Command (Mac) while selecting.
