Can I apply again if my application is rejected once?

In general, most credit providers may allow you to apply again after 30 days if your application is rejected once. However, it could be a good idea to understand why your application was rejected (e.g. your home country credit score is lower than required for that credit card, you couldn’t provide documents to prove your residential address or identity, you submitted an incomplete application etc.). Rectifying the reason and then re-applying, or applying for another card more suited to your profile, is more likely to result in a favorable outcome if your application has been rejected once.
