The exhaustive document checklist organized by slip color — every paper, portfolio link, and social media handle consulates are requesting in 2026.
When you receive a 221(g) slip, the documents you submit can make or break your case. In 2026, consulates are requesting more documentation than ever — including GitHub portfolios, social media handles, and detailed project architecture diagrams. This checklist covers every document you might need, organized by slip color and situation, so you can respond completely the first time and avoid delays from incomplete submissions.
Workers at these companies frequently need 221(g) document preparation. Even at major employers, consulting and third-party placement roles trigger document requests.

| Tata Consultancy Services | 28,950 |

Consulates in India — particularly Chennai, Hyderabad, and Mumbai — have significantly expanded their documentation requirements in 2026. The most notable change is the growing emphasis on technical portfolio evidence. Consular officers are now routinely asking STEM workers to provide links to their GitHub repositories, published research papers, or online technical portfolios as proof that they possess the specialized skills described in their petition.
Social media verification has also intensified. Every handle listed on your DS-160 must be accessible — deactivated or private accounts raise flags. Officers cross-reference your LinkedIn employment history with your petition details, and inconsistencies trigger additional scrutiny. If you listed a Twitter/X account, ensure your posts do not contradict your stated employment history or travel timeline.
Regardless of your slip color, prepare these documents before submitting anything:
Blue slip requests are specific. The slip itself lists exactly what is needed. Common requests include:
Yellow slips require you to prove that your job is a genuine specialty occupation and that the employment relationship is legitimate. This demands more detailed evidence:
Starting in 2024, the DS-160 requires listing all social media handles used in the past 5 years. In 2026, consulates are actively verifying these:

The best defense against 221(g) is a well-prepared petition. Companies with dedicated immigration teams file cleaner petitions with fewer documentary gaps. Search Wisa to find employers with proven sponsorship track records and strong filing histories. Search H-1B sponsors on Wisa →

For consulting roles, the client letter is critical — it must name you specifically, describe your project, and confirm the client's awareness of the H-1B arrangement. Submit everything listed on the slip in a single, complete response to avoid further delays.
In 2026, consulates — particularly Chennai and Hyderabad — are increasingly requesting GitHub profiles or technical portfolios from STEM workers. While not always listed on the slip itself, having an active GitHub with repositories in technologies matching your job description significantly strengthens your case. If you work with proprietary code, create a personal portfolio showcasing your skills with sample projects, open-source contributions, or technical blog posts.
Submitting incomplete documents extends your processing time significantly. The consulate may request additional documents (adding another 30-60 days), or worse, deny your visa if the documentation fails to address their concerns. Always respond with a complete package the first time. If you are unsure what is needed, consult with your immigration attorney before submitting. It is better to take an extra week to prepare a complete response than to rush an incomplete one.
Absolutely not. Deleting or deactivating social media accounts listed on your DS-160 is one of the fastest ways to trigger a 221(g) hold or even a pink slip referral. Consular officers check these accounts, and a deleted account raises immediate suspicion. Instead, review your accounts for any content that contradicts your petition or visa status, and set appropriate privacy settings — but keep the accounts active and accessible.
