Legal help for Austrian Self-Support Residence Permit (Niederlassungsbewilligung – ausgenommen Erwerbstätigkeit)

Hello,
I am currently living in Dubai and would like to apply for an Austrian self-support residence permit for myself and my spouse. My Nationality is Iranian / Dominican (Second Nationality)
I am the founder of an international brokerage and crypto-fintech company registered in Comoros, with regular income in AED (UAE dirhams).

We plan to relocate to Vienna within the next few months and want to ensure that our application meets all financial and legal requirements.

I am looking for a licensed attorney in Austria who can represent us before MA35 Vienna, review our documents (proof of funds, bank statements, business registration), and handle the residence application process.

Please let me know your availability for a consultation and your fee structure.

Thank you,
Ali Asgari
