Is ṣadaqah obligatory for an expatriate with a low salary working in Kuwait, and what are the conditions under which ṣadaqah becomes obligatory for individuals?

Charity (sadaqa) is one of the greatest acts of drawing closer to Allah, and it is recommended for every deserving person, regardless of their nationality. If it is a financial charity (zakat), it is obligatory upon the wealthy, and it is permissible to give it to poor Muslims.
