Yes, there are 2 old concepts which are used by most countries. 1) Jus sanguinis (latin for blood ties or right of blood), this means u get citizenship if one of your parents is a citizen of country X. 2) Jus soli (latin for right of the soil), which means u get citizenship by the territory you are born on. Both countries the USA and Germany nowadays have a mix of those, Germany had 1. back in the day and then introduced 2. over time, also special foreigner laws like getting a permant residency permit quiet eaily after you have been there for 8 years. SEA especially Thailand has still only 1. so it's quiet impossible to get permant residencies till today - but fear not, you can bribe urself in paying money and its called the thai elite card -.-
