Overall timing
Preparing documents usually takes 1–3 weeks. Embassy decision times vary widely by post — some decide within days, others take several weeks.
Advice from our team
- Read the checklist published by the specific post; requirements differ between embassies
- Keep employment and financial evidence consistent — conflicting figures invite questions
- Start legalisation of foreign documents early; it is usually the slowest element
Things to watch out for
- No one can guarantee a visa outcome; the decision belongs to the reviewing officer
- Submitting inaccurate or altered documents can lead to refusal and future entry problems
- Rules and checklists change; always verify against the official source before filing
Frequently asked questions
Can you guarantee approval?
No. Approval is entirely at the discretion of the embassy or Immigration officer. We focus on accuracy and completeness of the file.
Do you file the application for me?
Most posts require the applicant to file in person or through the official portal. We prepare, translate and certify the supporting pack.
Which documents need notarisation?
Typically foreign-issued documents such as degrees, police clearances and relationship certificates. The exact list depends on the post.
