Family reunification remains one of the most common paths to US immigration.

The Diversity Visa (DV) Lottery, also known as the Green Card Lottery, grants 50,000 immigrant visas annually to applicants from countries with low rates of immigration to the US.
While the application is free, it’s easy to make mistakes that lead to disqualification, such as incorrect photos or incomplete details. This is why many applicants choose to use professional services like the US Green Card Office, which assists with photo verification, form submission, and eligibility review.
Applicants must meet educational or work experience requirements and be born in an eligible country.
Key Points:
- Registration typically opens in October each year.
- Results are announced in May of the following year.
- Individuals who are selected can apply for permanent residency through a US embassy or consulate.
D. Special Immigrant and Returning Resident Visas
- Extraordinary Immigrant (SI): Religious workers, certain US government employees, and translators.
- Returning Resident (SB-1): Lawful permanent residents returning to the US after extended stays abroad.
3. Choosing the Right Visa
Selecting the correct visa depends on your travel purpose, duration of stay, and long-term plans.
- For short visits → Nonimmigrant visas like B-1/B-2.
- For educational purposes, F, M, or J visas are available.
- For temporary employment → H, L, O, or P visas.
- For permanent residence → Family, Employment, or Diversity Visa Lottery.
Always ensure your visa intent aligns with your declared purpose. Misrepresentation can lead to permanent bans.
4. Common Mistakes to Avoid
