I understand your situation, and now based on the answers to your questions, I have a certain understanding of pure white households.
First of all, white households can apply for a credit card, but the limit is not very high, only around 10,000.
Secondly, it is possible to apply for a large-amount credit card for a white household, but it generally requires packaging, and the price is very high. Personally, I suggest that if there is nothing urgent, it is better not to apply. The fastest processing time is 3 days to seven days, and it can also take 15 days or 20 working days.
Finally, large credit cards are all issued by people with financial resources, such as cars, houses, social security, etc. In a situation like yours, it is not easy to apply for it.
I hope my answer can help you! If you still don’t understand, you can continue to ask me!
