Ds160 Autofill

DS-160 Auto-fill Skill

This skill automates the filling of US nonimmigrant visa DS-160 forms by combining:

• CDP (Chrome DevTools Protocol) for fast element location
• CSV data source for user information
• LLM assistance for complex cases (captcha, missing elements)
• Session persistence for resume capability
• Chinese to English translation for user input

Quick Start

Starting a New Application

1. Provide CSV data: User must provide a CSV file with their personal information (use ds160-user-info.csv as template)

2. Open DS-160 website: Use browser tool to open https://ceac.state.gov/genniv/ with profile openclaw

3. Initialize session: Load and execute scripts/ds160-filler.js to parse mappings and CSV

4. Start filling: Begin with the home page, handle captcha with LLM, then proceed page by page

Resuming an Application

1. Load existing session: Check ds160/ds160-session.json for saved Application ID

2. Open application: Use the saved Application ID to resume on DS-160 website

3. Continue filling: Load CSV from saved location and continue from last page

Core Workflow

Step 1: Prepare Data

Always check if session exists first:

// Read ds160/ds160-session.json
// If exists → Resume mode
// If not → New application mode

New application mode:

• Ask user for CSV file path or content
• Save CSV to ds160/ds160-user-info.csv using write tool
• Initialize session data in ds160/ds160-session.json:

  {
    "applicationId": null,
    "securityQuestion": null,
    "securityAnswer": null,
    "currentPageIndex": 0,
    "completedPages": [],
    "startDate": "2026-02-06T21:00:00Z"
  }
  

Resume mode:

• Load CSV from ds160/ds160-user-info.csv
• Load session from ds160/ds160-session.json
• Report current progress to user

Step 2: Initialize Browser

// Open browser with openclaw profile
browser_start: { profile: "openclaw", targetUrl: "https://ceac.state.gov/genniv/" }

// For resume mode, add Application ID to URL
// Example: https://ceac.state.gov/GenNIV/Common/ConfirmApplicationID.aspx

Step 3: Fill Current Page

For each page in sequence:

1. Snapshot page to understand current state:

   browser_snapshot: { refs: "role", profile: "openclaw" }
   

2. Load mappings from references/ds160-elements.yaml

3. Execute fill logic using browser act with evaluate:

   // Load ds160-filler.js
   // Call fillPage(page, currentUrl, userData, yamlData)
   

4. Handle results:

   • Success: Continue to next page
   • Needs LLM assistance: Call LLM and retry
   • Needs user input: Save progress and pause

Step 4: Handle Special Cases

Captcha:

• Take screenshot of captcha area
• Use image tool to analyze captcha
• Fill captcha code via browser evaluate

Missing element:

• Call LLM with page snapshot
• Ask LLM to locate element and provide alternative selector
• Retry fill operation

Translation needed:

• Call LLM with field context and Chinese value
• Ask LLM to translate to appropriate English value
• Update CSV and retry fill operation

Missing user data:

• Identify which field is missing
• Report to user with field name and description
• Important: Save current page using browser evaluate before pausing
• Wait for user to provide data

Step 5: Save Progress & Continue

After completing a page:

1. Update session data:

   {
     "applicationId": "AA00FBLCQP",
     "securityQuestion": "What is the given name of your mother's mother?",
     "securityAnswer": "LiMei",
     "currentPageIndex": 5,
     "completedPages": ["home", "security_question", "personal_1", "personal_2"],
     "startDate": "2026-02-06T21:00:00Z"
   }
   

2. Save to file: write(ds160/ds160-session.json, JSON.stringify(sessionData))

3. Report progress to user:

   • Current page completed
   • Next page name
   • Application ID
   • Security question/answer (first time only)
   • Overall progress (X/Y pages)

4. Click "Continue" button to proceed to next page

Data Structures

CSV Format

The CSV must have these columns:

1. 页面 - Page name
2. 字段名称 - Field identifier (matches YAML name field)
3. 英文说明 - English description
4. 中文说明 - Chinese description
5. 必填 - Required? (是/否)
6. 示例值 - Example value
7. 用户填写 - User-provided value (this is what gets filled)

Important: Users can provide values in Chinese. The script includes a built-in translation dictionary for common fields (gender, marital status, countries, etc.). For fields not in the dictionary, LLM will be called for translation automatically.

YAML Structure

Each page in ds160-elements.yaml contains:

• page_id: Unique page identifier
• page_name: Human-readable page name
• url: Page URL pattern
• elements: Array of form elements with:
  • id: Element ID
  • name: Field identifier (matches CSV)
  • type: Element type (text, select, radio, checkbox, button)
  • label: English label
  • label_cn: Chinese label
  • required: Is required?
  • options: Available options (for select)
  • group: Radio group name

Error Handling

Element Not Found

Symptoms: fillPage returns needsLLM: true

Action:

1. Take page snapshot
2. Call LLM with:
   • Current URL
   • Element information (id, name, type)
   • Page HTML snippet
   • Ask LLM to analyze and provide alternative selector
3. Retry with LLM-suggested selector

Translation Needed

Symptoms: fillPage returns needsTranslation: true

Action:

1. Call LLM with translation context:
   • Field name and description (EN/CN)
   • Field type and available options
   • Original Chinese value
   • Ask LLM to translate to appropriate English value for the field
2. Update CSV with translated value
3. Retry fill operation with translated value

Example LLM prompt for translation:

I need to translate this Chinese value for a DS-160 form field:

Field: ${elementName}
Type: ${elementType}
English label: ${label}
Chinese label: ${label_cn}
Chinese value: "${originalValue}"

Available options (if select): ${options}

Please provide the correct English value for this field. Consider:
- The field type and context
- Available options (if applicable)
- Standard DS-160 terminology

Return only the English value, no explanation.

Data Missing

Symptoms: fillPage returns needsUserInput: true

Action:

1. CRITICAL: Save current page before pausing:

   // Find and click "Save" button
   browser_act: {
     request: { kind: "click", ref: "save_button" }
   }
   

2. Report missing field to user:
   • Field name (English and Chinese)
   • Description
   • Whether it's required
3. Update CSV with new data using write tool
4. Resume filling

Captcha

Symptoms: Captcha image detected on page

LLM Integration

When to Call LLM

1. Captcha detection: Always use LLM to read captcha
2. Element not found: When multiple locator strategies fail
3. Translation needed: When user provides Chinese value not in built-in dictionary
4. Complex elements: For elements that require understanding context
5. Validation errors: When form submission fails with unclear reason

LLM Prompts

For element location:

I need to find this form element on a DS-160 page:
- Element ID: {elementId}
- Field name: {fieldName}
- Element type: {elementType}
- Current URL: {url}

Please analyze the page and provide:
1. The correct way to locate this element (CSS selector or JavaScript)
2. Any visible labels or text associated with it

For captcha:

Please read the captcha code from this image. Return only the code characters, no explanation.

Session Persistence

Session file location: ds160/ds160-session.json

Session data structure:

{
  "applicationId": "AA00FBLCQP",
  "securityQuestion": "What is the given name of your mother's mother?",
  "securityAnswer": "LiMei",
  "currentPageIndex": 5,
  "completedPages": ["home", "security_question", "personal_1", "personal_2", "travel", "travel_companions"],
  "startDate": "2026-02-06T21:00:00Z",
  "lastUpdated": "2026-02-06T21:30:00Z"
}

When to save session:

• After completing each page
• Before pausing for user input
• After receiving Application ID
• After setting security question/answer

Browser Automation Notes

Always use openclaw profile to maintain session across pages.

Use browser act with evaluate for form filling:

• More reliable than individual click/type actions
• Can execute complex JavaScript
• Better error handling

Use browser snapshot before each page:

• Check page state
• Identify dynamic elements
• Verify page loaded correctly

Testing Checklist

Before using this skill with real data:

• Test element location on each page type
• Verify CSV parsing with sample data
• Test captcha handling with LLM
• Verify session save/load functionality
• Test resume from middle of application
• Verify "Save" button clicking works before pauses
• Test with various element types (text, select, radio, checkbox)
• Verify progress reporting format
• Test Chinese to English translation

Files Reference

• scripts/ds160-filler.js - Core automation logic (run via browser evaluate)
• references/ds160-elements.yaml - Element mappings (read-only)
• references/ds160-user-info.csv - User data template (copy to workspace)
• ds160/ds160-session.json - Session persistence (auto-created)
• ds160/ds160-user-info.csv - Active user data (auto-created)

Important Notes

• NEVER submit the final form - this is for automation/testing only
• Always save before pausing - prevents data loss
• Report progress frequently - at least every page
• Keep Application ID secure - it's sensitive information
• Use fake data for testing - don't use real personal info
• Chinese input is supported - use built-in dictionary or LLM for translation
