We recommend you to add the ID document that belongs to your current country of residence, as this will make it easier to verify attributes such as your home address.
It may be worth considering which attributes you will need to share, if you are creating a Yoti to share attributes with a business. For example, if Nationality is a required field, then it would be better to add the document that contains it. To see which attributes we take from which document, please feel free to check out this link here.
