There are some immigration programs which require proof of funds from an applicant to determine whether he/she can afford the expenses in the country; he/she is planning to immigrate during the initial period. So, in case you don’t have adequate funds to show to the immigration officer, then you have to face rejection.
Information provided in the application represents the candidate so, make sure that information is correct and valid. If the immigration authority finds any information wrong or incorrect during verification, then they can reject the application.
However, rejections or refusals are not permanent. Depending on the case and type of visa application, different options are available including appealing, re-applying, and reconsideration. So, instead of losing hope, it is better to contact an experienced immigration consultancy which can analyze visa refusal case and accordingly guide you the best approach for the same.
