Question 3

What is the difference between visa on arrival and e-visa?

Accepted Answer

Visa on arrival (VoA) means you obtain your visa at the airport or border upon arrival - no advance application required. An e-visa (electronic visa) requires you to apply and receive approval online before you travel. Both allow entry but e-visas must be secured in advance.

Question 4

What is citizenship by investment?

Accepted Answer

Citizenship by investment (CBI) allows foreign nationals to obtain a second passport by making a qualifying investment - typically a donation to a national development fund or real estate purchase. Popular programs include those in the Caribbean (St Kitts, Grenada, Dominica) and Europe (Malta, Vanuatu). Costs typically range from $100,000 to $1,000,000+.

Question 5

What is a golden visa?

Accepted Answer

A golden visa is a residency-by-investment program that grants long-term residency (and sometimes a path to citizenship) in exchange for a qualifying investment such as real estate, business creation, or government bonds. Popular golden visa countries include Portugal, Spain, Greece, UAE, and Malta.

What is an eTA (Electronic Travel Authorization)?
