After being accepted for a credit card, with a $30k limit, I used it to charge for about a month. No problems. Booked tickets and traveled to a foreign country. Again no problems... For a few days. Then it stopped working. No notice, just stopped. App and account just showed "restricted." Called to get the restriction lifted, thinking they'd flagged a foreign charge as fraud (with no way to tell them I'm traveling, they claim it's unnecessary), and they want: copies of passport, birth certificate, SSN card, utility bill, and more, all while I'm traveling. Non-negotiable; they cannot accept anything except all those documents. Capital One was perfectly happy to strand me in a foreign country with no credit card, despite having worked and processed charges for over a month, and several days of traveling. DO NOT USE.
