The general rule with cap one is that you can only open 1 account every six months.
I have read a few posts though where some were able to get 2 in a day, though I am not sure how.
Here's a post about the 1/6 rule https://www.doctorofcredit.com/capital-one-tightens-churning-rules/
Typically to combine inquiries, you app on the same day and fail close together in time. This does not seem too common though for CO since they will likley just deny the second app and not process it at all.
Cap One limits you to a new credit card every 6 months.
Congrats
check discover prequalification.
use you cap one card every day. pay if off every time you hit 500 balance before the statement cuts. pay off the week after any balance hits your cr from the statement.
cap one can grow. you may have to open additional cards but cap one can grow.
I went from 3k to 80k in 4 years with Cap One (plus a 2.49% apr car loan for 72 months)
good luck and stay away from store cards you dont need or get a huge advantage from (5% lowes, 5% amazon, 0% offers, etc.)
stay away from pred cards.
check Merrick bank also.
Good luck.
