All wages and any other compensation for services performed in the United States are generally considered to be from sources in the United States. The place, where the personal services are performed, generally determines the source of the personal service income, regardless of where the contract was made, or the place of payment, or the residence of the payer.
Affiliate and referral marketing involves driving sales for another business which then pays you a commission for each sale it acquires through your efforts. The Amazon Associates affiliate marketing program is one of the best options for people looking to earn money this way. You need set up a website with outbound links redirecting to products on Amazon (or another site that offers affiliate programs) and if a visitor from your site buys the product, then that business pays you a share of the amount spent.
Agriculture is an important part of the Indian economy. At around 1,530,000 square kilometres (590,000 sq mi), India has the second-largest amount of arable land, after the US, with 52% of total land under cultivation. Although the total land area of the country is only slightly more than one third of China or the US, India's arable land is marginally smaller than that of the US, and marginally larger than that of China. However, agricultural output lags far behind its potential.[367] The low productivity in India is a result of several factors. According to the World Bank, India's large agricultural subsidies are distorting what farmers grow and hampering productivity-enhancing investment. Over-regulation of agriculture has increased costs, price risks and uncertainty, and governmental intervention in labour, land, and credit are hurting the market. Infrastructure such as rural roads, electricity, ports, food storage, retail markets and services remain inadequate.[368] The average size of land holdings is very small, with 70% of holdings being less than one hectare (2.5 acres) in size.[369] Irrigation facilities are inadequate, as revealed by the fact that only 46% of the total cultivable land was irrigated as of 2016,[158] resulting in farmers still being dependent on rainfall, specifically the monsoon season, which is often inconsistent and unevenly distributed across the country.[370] In an effort to bring an additional two crore hectares (20 million hectares; 50 million acres) of land under irrigation, various schemes have been attempted, including the Accelerated Irrigation Benefit Programme (AIBP) which was provided ₹80,000 crore (₹800 billion) in the union budget.[371] Farming incomes are also hampered by lack of food storage and distribution infrastructure; a third of India's agricultural production is lost from spoilage.[249]
Ebooks are one of my favorite sources of passive income. Now, you can do this the simple way and just publish it on Amazon's KDP. Or, you can go all out and build yourself a book funnel. Book funnels are powerful, but they won't be fully passive. For example, if you do a free-plus-shipping offer for your ebook (converting it into a physical book), you'll need to create some one-time offers (i.e. extra training) and up-sells (i.e. an audiobook). But, a book funnel can be very powerful.

These days, low-risk bond yields aren’t enough to meet most income needs. When investing in bonds, the income typically comes as coupon payments – contractually guaranteed interest payments at predictable intervals.  There are many kinds of bond income available, so you must strike a balance between reaching for higher income (yield) and limiting risk.
