| Aspect | H1B Visa Transfer | H1B Visa Extension |
|---|
| Purpose | Change of employer while maintaining H1B status | Renewal of existing H1B visa validity period |
| Process | File new petition with new employer; approval allows work with new employer | File extension petition with current employer; extends stay |
| Credentials | Same as initial H1B, including employer-specific requirements | Same as initial H1B, focusing on maintaining current employment |
| Work environment | Switching employers within the same industry or sector | Continuing employment with the same employer |
In summary, an H1B Visa Transfer involves changing employers while maintaining your visa status, whereas an H1B Visa Extension extends your current visa validity with the same employer. Both processes require specific filings but serve different purposes in your employment journey.
