Which of the following aligns with the issuance of immigrant visas?

The issuance of immigrant visas is indeed consistent with the ability to be processed at multiple international posts. This means that applicants are not restricted to a single location for submitting their visa applications; they can choose from numerous U.S. embassies and consulates around the world. This flexibility is crucial as it accommodates the diverse locations of applicants, allowing them to submit their paperwork, attend interviews, and obtain their visas more conveniently.

Other answers do not align with immigration visa issuance policies. The option about being limited to U.S. citizens is incorrect since immigrant visas are actually intended for foreign nationals seeking to immigrate to the United States. The requirement for a mandatory interview is common and crucial, but not universally applicable to all categories of visas; thus, stating it as if it applies to all would be misleading. Lastly, all visa applications, including immigrant visas, undergo background checks to ensure the safety and security of U.S. borders, making the statement about not being subject to background checks incorrect.
