second, the line of each bank does not affect, but your first card is too low, and the second card-issuing bank will see it, so I won't give you too high a line now.
Third, there are skills in filling in the credit card application form:
1. Marital status: Married with children scored the highest because it was relatively stable.
2. Education: Higher education will add points, at least bachelor degree or above.
3. Residential status: self-purchase without loan, plus points. Explain that the economic strength is good and there is no burden.
4. Personal annual income: The more, the better. Don't exaggerate.
5. Time of residence at current address: the longer the better, and be careful not to be outrageous.
6. Working hours in the current unit: at least one year, the longer the better.
7. Occupation and industry category: institutions, state-owned enterprises, top 5 enterprises and well-known enterprises are the best (it is best not to write about financial companies).
8. mailing address: it is best to choose the address of the company, which can earn extra points.
