For PR, You need:
IELTS score L8R7W7S7
WES evaluation
Work experience certificate from the clinic where you work. Job duty letter according to IRCC requirements.
Proof of payments from the clinic (bank statement showing entries of cheques deposited, pay stubs, etc)
If you are single, 6.5 to 7 lakhs in your bank account. I would advice to get this amount in your bank account right away so when you prepare your profile and show bank statement, your account will have this amount for a period of more than 6 months. There are various ways to show proof of funds if you are getting this amount from your family. (Gift deed from family members, Sale of assets like property, gold, mutual funds etc)
Make sure all your certificates, documents and passport have the same name without variations. If not, get a 'one and the same person' affidavit.
For NDEB process:
