Anonymous participant HCMC can be ok, some recent posts show requests for proof of income for DTV, others get approved with no questions asked. Make sure you have a 6 months or more course.
Not saying there are many but there have been obvious false posts made and many spotted the lies. There are much less of those silly posts nowadays e.g having a business class tickets eases arrivals for DTVERS.
Anonymous participant Not all embassies are as demanding as Taipei. You are right SP can be just an additional fee, paperwork etc.. There are embassies you can just submit the SP paperwork like Jakarta. Where are you applying?
