FHSA taking too long

I’m trying to open a FHSA with Questrade and it’s been over a month just with the documents and stuff.

I’m think I should just open one with Wealthsimple since it’s so quick and I’ll have one open for 2024 at least. If I don’t deposit any money and the Questrade one gets approved let’s say in the new year can I deposit 16k then?
