Can an authorised representative handle the whole document chain for a partner or spouse visa for the United States?

From the visa files we prepare documents for every week, Risk control: group the file into identity/status documents, relationship or purpose documents, and financial documents, then apply the same certification level across each group. This makes cross-checking straightforward for the assessing officer and reduces requests for further information. We handle the document side of a visa file only — translation, Notarial Services Attorney certification, MFA legalisation and embassy attestation. We do not give immigration legal advice and never promise an approval outcome. Tell us the destination country and visa subclass and we bundle translation → notarisation → MFA legalisation → embassy attestation in one run.
