Have you ever thought about that you could deliberately give birth to your child in a certain country so that it would get citizenship there? Perhaps you have heard stories of pregnant Mexican women who ran, climbed and swam across the border into the US so that their children could get citizenship there and the whole family would get residency? By the way, that doesn't work anymore in the US. If a baby is born there, the baby will get the citizenship, but it will not give the family residency. At least not while the child is a minor.
In some countries, though, this still works. A baby being born in such a country, will get the citizenship and that will give the whole family residency. Examples of this are Mexico, Peru, Argentina and in general many Central and South American countries. So there can be tremendous benefits to giving birth in certain countries. Having a citizenship can also be a burden, though. An example are the US. Being a US citizen will make you have to pay taxes for life in the US, even if you reside somewhere else.
Here's some general background information on the two different main ways in which a child can acquire citizenship of a country: In some countries, citizenship can be acquired by being born in a country. This legal principle is called "jus soli", the right to a citizenship by birth on the soil of that country. Citizenship can also be acquired through the fact that the parents hold a citizenship, which the child will then also receive. This legal principle is called "jus sanguini", the right of blood. The idea behind it is that a baby has the parents' blood and thereby their nationality.
Often there is a certain mixture of these two legal principles.
Here you will find a list of countries in which a child born there to foreign parents receives or can receive citizenship. Sometimes this is linked to further conditions, e.g. that the parents had a residence permit:

The countries without further conditions other than birth there are mainly North, Central and South American countries, almost all of them. However, this possibility, as far as I know, also exists in Tanzania, Lesotho, Chad, Pakistan. As mentioned, this does not automatically in all those countries give the familiy residency. But in some. It depends on the country. Also, while in many countries dual citizenship is allowed, in others the child would have to choose one, when the child reaches the age of majority.
As mentioned, a child's citizenship does not automatically mean that the child's parents will get a residence permit. In Canada and the USA, for example, this was reportedly quite easy in the past, but no longer. The children can make use of their Canadian or US citizenship only when they are of age.
From Mexico and Peru, on the other hand, I have heard several reports of families who obtained residence permits in these countries by giving birth to children who thereby acquired the respective citizenship. And it was a relatively easy straight forward process.
I am continuosly collecting further reports on this subject from various countries, so please send me yours!
And before you want to give birth to your child in a certain country, please do find out for yourself exactly what the current conditions and rules there are.
