i had to get a secured card in order to build my credit. Used it for a year, made payments on time and then my credit score went from a 4 to a 790. Now i have cc offers left and right .
I would advise you to keep the secured card open and have some activity for at least 6 months . After that you can try getting a cc with capital one . also having too many hard inquiries on lowers your credit score and stay on your credit report for 2 years.
