 Trustindex verifies that the original source of the review is Google. I’m really happy to finally say that my 482 visa has been granted. It honestly felt like a long rollercoaster, especially with the waiting time from immigration, but Nathan was always there throughout the whole process.
After my previous visa refusal, I was really stressed and worried about what would happen next. When I met Nathan, he made things feel a lot more manageable. He’s very easy to talk to, knows what he’s doing, and gave me confidence when I needed it most.
My case wasn’t simple and there were quite a few tricky documents, but he handled everything calmly and professionally. I never felt lost in the process because he always guided me and explained things clearly.
I’m truly grateful to Nathan and the team at Cornerstone Migration for helping me get through this and finally secure my 482 visa. It means a lot to me.
I would definitely recommend Nathan to anyone who needs migration help — especially if your situation is complicated or you’ve had issues before.
Looking forward to working with him again for my PR pathway when the time comes.
Thank You Nathan
