For a person obtaining either an immigrant or nonimmigrant visa at a US consulate overseas, they may face obstacles and delays. Consular Processing has become increasingly complex and requires a high degree of competence and attention to detail to ensure a smooth process. The National Visa Center is much more demanding regarding the required supporting documents, including police clearances. Each consulate has unique procedures and requirements.Visa applicants at some consulates face a higher degree of scrutiny due to a skepticism at those embassies that has resulted from a history of fraud at countries. For cases originating in these countries, it is particularly critical to have a reputable and proactive attorney.
