What are my next steps, now that we got the initial approval email?

We applied for GV by investing in a IMGA Ações Portugal A Fund during last week of dec 2021. Couple of days ago my attorney forwarded this email for 3 of us

Informamos que, em 18-09-2023, foi admitida a candidatura de Autorização de Residência de Investimento (ARI) a My Name, nacional de ÍNDIA
A partir desta data poderá proceder ao agendamento da sua deslocação a um posto de atendimento do Serviço de Estrangeiros e Fronteiras.

Couple of questions:

  • We live in canada with indian passport, is there anything we need to do now while we wait for biometrics appointement?
  • The approval included me, my wife and my son but they are asking for proof that we support my wife’s mother. What documents can we provide to prove that she is dependent on us? My wife has no siblings and her father passed away few years ago.
