Hi,
As called out earlier, 5th lord of Procreativity/Progeny is Neecha or debilitated in your birth-chart and the aspect of Saturn/Shani-dev has perhaps contributed to the delay. But then, I’m inclined to think you have Yogas for parental pleasure. Kindly share birth-details of your wife (along with some background and major events of your/wife’s lives), to validate collective Karma – in case you are interested.
In my humble opinion, I think you can make it happen, if you are able to get past/over the fascination of Foreign/Overseas/Distant land and other such feelings/attachments, that seem to be clouding your mind. In any case, it looks like there might be a brewing opportunity for change in job/place with the onset of Mars/Kuja Maha-Dasha (starting from later part of 2028). Returning to India could materialize thereafter.
All said and done, there are a bunch of other factors that need to be checked validated, including the need for factoring in the concept of Desha-Kaala-Patra – something that is not easy over a virtual internet forum.
Take care…
