Hi Ramesh !!
Difficult to say.
Seem for me that off shore remote for freelance in pure non IT engineering is not here.
There's a lot of work to be done in engineering (design, mechanical, analysis, FEA, CFD...).
As I coach startup, I see on the IT side more and more company 100% remote.
If people want to join me on long journey, I will be pleased to set up a 100% remote engineering company: the software are here, we can connect expert to new graduates. Let's go !
