OTCQB is not an exchange. NYSE and NASDAQ are the only "Stock Exchanges" that "list" shares for trading. They are "SROs". The OTC BB and the OTCMarkets.com are software platforms for market makers to quote and execute trades.
Too many people pump some idea that they are exchanges. They are not self regulated, they are not exchanges, and they do not list shares.
If you do not know that by now, you need to go take a tour of the NYSE in the gallery and ask some tour guide who knows more about listing of shares on actual exchanges that stock promoters who scheme and scam money from unsuspecting investors.
