Switching from work visa to investor visa

1) There is no transfer.  You apply for a new investor visa once current visa is cancelled. When it is issued, you have to apply for dependent visa

2) All of this can be done online in EMS which you should sign up for with LMRA once your CR is active

3) For dependent visa, make sure that birth and marriage certificates are attested.................by MOFA Bahrain as well

For investor visa in my case do I need my address updated on CPR?

No

You will need to find another employer and they can apply for a visa.

If I want to take investor visa then???? What is the procedure of cancellation of job visa tell me hr saying I need to show return air ticket to them

For information on investor visas read this https://www.expat.com/forum/viewtopic.php?id=750635.

It's typical for HR to handle visa cancellations. They may request a return ticket to ensure that you depart the country once the visa is cancelled.
