Submission of all the required documents in time makes your task easier to get the visa. Late submission of documents, incorrect paperwork leads to reasons for K1 visa rejection. Sometimes people hire lawyers to get the visa issued and concerns of the United States Citizenship and Immigration Services (USCIS) remain unaddressed due to inattention of the lawyer’s office. The lawyer may not understand your situations properly and may not present them appropriately. This puts you in an awkward situation while facing the interview. It is better to handle visa issuance task by the couple.
As a U.S. citizen, your fiance/fiancee should be financially sound enough. If the financial statements furnished before the consular officer show that the U.S. sponsor is not able to bear the expenses of the applicant, the visa application is rejected.
Large age gap between the couple may not build a strong relationship. The age difference makes one of the reasons for K1 visa rejection.
The consular officer tries to know to when the couple had last met after filling I-129F K1 visa request and information regarding communication between them in previous year. The extent of contact also counts for a healthy relationship and consulate considers minimal communication between the couple to be one of the reasons for K1 visa rejection.
When the partners are not speaking same language or the applicant has poor English skills.
During interview, if the performance of the applicant is not satisfactory, the consular officer suspects the relationship and denies the visa.
If the consular officer finds any criminal record of the applicant, the visa request gets denied and violation of visa rules may be one of the reasons for K1 visa rejection.
