Why You Need an Immigration Lawyer for Permanent Residency
While it’s possible to submit an application on your own, immigration systems in countries like the UK, USA, and Canada have become increasingly complex. A single error — wrong document, missing signature, incorrect form, or outdated requirement — can lead to:
❌ Application rejection
❌ Delays of 6–24 months
❌ Loss of government fees (often non-refundable)
❌ Travel restrictions
❌ Ineligibility for reapplication in serious cases
Professional immigration lawyers help you:
- Understand eligibility requirements
- Prepare documents and supporting evidence
- Meet strict government deadlines
- Improve the strength of your application
- Avoid refusals and administrative errors
- Navigate appeals and reapplications if necessary
