What Each Immigration Form Does and Who Files It

DS-160 is the Online Nonimmigrant Visa Application completed by every applicant for a tourist, student, or work visa at a US consulate abroad. It captures biographic information, travel history, security background checks, and the purpose of your visit. Consular officers base their interview questions heavily on your DS-160 responses — inconsistencies between your answers and your supporting documents are the top reason for denials under 214(b) refusal.

Form I-129 is the Petition for a Nonimmigrant Worker, filed by a US employer (or in some cases an agent) on behalf of a foreign national seeking H-1B, L-1, O-1, TN, or E-2 classification. The I-129 is the foundational document for most employment-based nonimmigrant statuses. Each classification has specific I-129 supplement requirements: H-1B requires a certified Labor Condition Application (LCA); L-1 requires evidence of the qualifying corporate relationship; O-1 requires evidence meeting the three-of-ten criteria. An incomplete I-129 triggers a Request for Evidence before any substantive adjudication begins.

Form I-140 is the Immigrant Petition for Alien Worker, filed by an employer to initiate the green card process for an employment-based immigrant. Unlike the I-129 (temporary status), the I-140 is an intent to immigrate. Once approved, the beneficiary can file I-485 Adjustment of Status if a visa number is available in their preference category and chargeability area.

Form I-485 is the Application to Register Permanent Residence or Adjust Status — the final step for green card applicants already inside the United States. The I-485 packet typically requires 18–25 documents including birth certificate, civil documents (marriage certificate, divorce decrees), Form I-693 medical examination by a USCIS-designated civil surgeon, Form I-864 Affidavit of Support from the sponsor, and evidence of the underlying I-140 approval. Concurrent filings for I-765 (employment authorization) and I-131 (advance parole) can be included in the same mailing.

Form I-765 is the Application for Employment Authorization, commonly called the EAD (Employment Authorization Document). The I-765 has over 30 eligibility categories, each with different required documents and processing times. Choosing the wrong category — even inadvertently — causes USCIS to reject the application or issue an RFE. The most common categories for immigration filers are (c)(3) STEM OPT extension, (c)(8) pending asylum applicant, (c)(9) pending adjustment, and (c)(11) parolee.

Common Form Mistakes That Trigger RFEs or Denials

For DS-160: listing a different employer than appears on the I-797, understating prior US stays (overstays trigger automatic bars), and inconsistent names across documents (including variations in spelling of your own name across different papers) are the most common refusal triggers.

For I-129: the leading RFE trigger is a job description that fails to establish "specialty occupation" — meaning the job does not require a bachelor's degree or higher in a specific field. Employers often write generic job descriptions that apply to any industry. USCIS wants a description that ties each duty specifically to a field of study. Second to that is the "employer-employee relationship" RFE: USCIS wants evidence the employer controls the work (supervision, work schedule, equipment provision, ability to fire).

For I-485: expired civil documents (birth certificates, marriage certificates), missing I-693 signed by a civil surgeon within 60 days of filing, and failure to list all prior US entries on the I-485 form are common RFE triggers. If you had any US entry that wasn't recorded on an I-94, consult an attorney before filing.

What the Free vs. Paid Tiers Cover

The free tier provides a field-by-field walkthrough of your selected form, flags fields where common mistakes cause RFEs, explains what each section of the form is asking for in plain English, and identifies documents you should prepare before filing. The paid tier ($29–$79 depending on form complexity) adds a complete pre-filing review, a structured evidence checklist organized by document category, and draft responses to every field so you can review and refine before submission.

The AI guidance is based on current USCIS form instructions, 8 CFR regulations, and AAO precedent decisions. It does not replace attorney review for complex cases — but it catches the 80% of mistakes that are routine and preventable.
