Thank you very much comrades.
Is there any final tips or advice for me and my wife since our interview is in a week time
In no particular order but the following could be helpful:
1. Be confident
2. Tell the truth
3. Go with as many supporting documents as possible that proves your relationship and qualification for the visa.
4. Get to the consulate on time.
5. Arrange your documents in an organised manner (eg. All educational documents in one one envelope or file) for easy reach out when called.
6. Go over all supporting documents a day prior to the interview.
7. Pray before the interview, it has a way of exuding confidence if you believe in prayer.
8.
DO NOT mix currencies meant for payment of visa fees (i.e. GHS and $), maintain
ONLY one set of currency.
9. Look into the CO's eye when talking to him/her and keep an inviting smile at all times.
10. Do not shake when further or additional questions are asked on a particular issue, just relax and answer confidently.
11. If under tension, take in periodic and slow breath-ins and outs in an almost hideous way.
12. go with the mindset of coming home with the good news!!
Cheers!!
