Now you are back in India. Immediately you should apply for the change of name in your passport. You can apply online under reissue of passport. You can apply offline also through Eseva centres. You have to fill the application form and the following documents are to be attached with the application. If you want to apply online you can scan and upload the documents. You can apply in the normal category or under the tatkal scheme also. You have to submit the following documents.

1. Original old passport.
2. Two copies of the first two pages and last two pages of the passport including ECR/Non-ECR page. All these copied should be self-attested by you.
3. Two documents either from school documents or public documents like Aadhaar/ PAN card as per the list that is given on their website.

As per your details it is clear that your name in the higher secondary certificate is wrong and in all other documents it is correct. If it is so then you have to again go for an affidavit regarding the incorrect name in higher secondary certificate. In the affidavit the details are to be given along with the correct name and copies of the supporting documents like Aadhar card and they should be made a part of it and should be duly referenced. Once this affidavit is signed by you and countersigned by the magistrate or notary public then you have to show it for the passport or Visa purposes.

Please note that the name should be consistent over all the documents and any mismatch will be a problem in getting Visa. What I will suggest is if your name in passport is in mismatch then you first change it using the affidavit and other credentials and then only apply for Visa. Clarity in documents is a very important thing for getting Visa. There are very experienced agents now a days available everywhere who can help you professionally to get these jobs done on payment of some fees. I will advise you to take their help to get your documents in order before applying for Visa. They will also help you in getting Visa.
