Salary And Experience Standard

• Salary is generally assessed against the annual MOJ GNI-linked E-7-1 benchmark.
• Special reductions/exemptions may apply to SMEs, venture firms, and non-capital-region employers when announced by MOJ.
• Degree/experience waiver cases can exist for high-salary or strategic-talent pathways, but require strong evidence.

Common Rejection Risks

• Degree/work history has weak relevance to the offered role.

Occupation-Specific Filing Notes

• Submit NDT-specific evidence: method certifications, inspection logs, defect-analysis reports, or QA acceptance records.
• Clarify the exact inspection methods you operate (UT, RT, MT, PT, etc.) and your responsibility level.
• Employer documents should explain why certified NDT capability is critical for current production or maintenance work.
