Generally speaking, the existence of credit card debt will have a certain impact, but it does not necessarily completely rule out your qualification as a loan guarantor. It depends on one's financial situation and debt situation. Some banks will consider the applicant's credit history, monthly income, debt ratio and other factors when considering the guarantor's application. Therefore, if you have good credit, stable income and low debt ratio, you may still be a loan guarantor for others. But if your credit is greatly negatively affected, you may not be approved as a guarantor. In short, being a guarantor for others needs careful consideration to ensure that its financial status and credit record meet the corresponding requirements and avoid causing too much financial risk to itself.
