Applying for a Green Card is a significant step toward building your life in the United States. Whether you are applying through the Diversity Visa Program (Green Card Lottery), family sponsorship, employment, or adjustment of status, the Green Card Application process requires careful attention. Even small mistakes can lead to delays, requests for additional documents, or complete refusal of your application.
This guide explains the most common errors applicants make and how to avoid them, helping you submit a complete and accurate application confidently.

1. Submitting Incomplete or Incorrect Forms
One of the most frequent mistakes is sending forms with missing information, outdated versions, or incorrect answers.
US immigration agencies do not notify you of minor errors; they reject or delay your case.
How to Avoid This:
- Always download forms directly from official US government websites.
- Double-check every field before submitting.
- Ensure all signatures are handwritten or digitally allowed where applicable.
- Review your answers for accuracy and consistency.
If applying through the Diversity Visa Lottery, professional review services like the US Green Card Office can help avoid common mistakes many applicants make when filing on their own.
2. Using Incorrect or Non-Compliant Photos
Your Green Card Application photo must meet strict US visa guidelines. Poor image quality is one of the top reasons for disqualification in the Diversity Visa Lottery.
Common Issues:
- Wrong background color
- Incorrect dimensions
- Shadows or filters
- Wearing prohibited accessories (e.g., hats, tinted glasses)
How to Avoid This:
Use a professional photo editor or photo verification service.
The US Green Card Office offers photo-checking tools to ensure your image meets the exact DV Lottery specifications helping you avoid rejection due to something preventable.
3. Missing Deadlines
The US immigration process is time-sensitive. Whether you are applying for adjustment of status, filing supporting documents, or checking Green Card Lottery results deadlines matter.
How to Avoid This:
- Track deadlines in a calendar.
- Check your application status regularly.
- If applying for the DV Lottery, remember:
- Registration happens once a year.
- Selection results must be checked manually online.
If you miss a DV entry window, you can still prepare early. The US Green Card Office accepts applications year-round, so people don’t forget the official registration period.
4. Failing to Prove Financial Stability
When applying for a family-based Green Card or through adjustment of status, applicants must show they can financially support themselves.
How to Avoid This:
- Make sure your sponsor meets the required income threshold.
- Include correct tax forms and proof of employment.
- If necessary, find a joint sponsor who meets the income requirements.
5. Not Preparing for the Visa Interview
The interview is a crucial step. Many applicants fail because they:
- Arrive without the required documents
- Cannot clearly explain their case
- Provide inconsistent answers
How to Avoid This:
- Practice explaining your purpose and background.
- Bring all original documents and copies of documents.
- Stay calm, honest, and respectful.
6. Providing False or Inconsistent Information
Any misrepresentation even accidental is considered serious.
It may lead to multi-year bans from entering the US.
How to Avoid This:
- Always tell the truth.
- Ensure all forms match your personal history exactly.
- Never use fake documents immigration officers verify everything.
7. Ignoring Requests for Additional Evidence
US immigration may send a Request for Evidence (RFE) if clarification is needed.
Many applicants miss or delay their responses, leading to denial.
How to Avoid This:
- Check email and case status weekly.
- Submit the requested documents before the deadline.
- Organize and label documents clearly.
