The K-3 visa is a temporary entry option for spouses of U.S. citizens, allowing the beneficiary to await the processing of their immigration petition while already in the United States. This process, like many others in the immigration field, involves a series of documentarily proven requirements, including the demonstration that the sponsor has the financial means to support the beneficiary.

In the case of the K-3, the sponsor usually needs to prove their financial ability to prevent the beneficiary from becoming a public charge. For this purpose, it is common for the submission of an affidavit of financial support to be requested. Traditionally, this affidavit is completed by filling out Form I-134, which serves to certify that the spouse residing in the United States has sufficient income or financial resources to maintain the beneficiary, thus covering potential public dependency risks.

It is important to highlight that requirements may be updated over time, and it is always advisable to stay alert to the most recent instructions published by the Department of State and the United States Citizenship and Immigration Services (USCIS). Staying informed and strictly following the country’s laws and regulations is essential to avoid delays or risks in the immigration process.

Therefore, seeking information from reliable and specialized sources can prevent falling into traps or marketing campaigns that promise miraculous solutions. If specific doubts arise or if there is uncertainty regarding the documents to be provided, it is worth resorting to consultations through official channels or specialized professionals, always being careful not to trust unreal promises about immigration process results.

In summary, yes, the sponsor of the K-3 visa normally must submit an affidavit of financial support – through Form I-134 – as part of the documents demonstrating their capacity to sustain the spouse beneficiary. Following the current legislation and using reliable sources is indispensable for the success of this procedure.
