I looked at the "Gair Aawasiya Nepali Sambandhi Niyamaawali 2066" (I just googled it by typing NRN 2066). Section 11 sub-section 1 on Page 4 and 5 mentions the areas of land that a NRN can purchase for his residence. This rule seems to be applicable to the time after acquiring foreign citizenship. However, the subsection 2 on page 5 mentions that if a foreign citizen of Nepali origin had acquired fixed assets in the capacity of a Nepali citizen, then sub-section 1 does not apply. I am interpreting this as the following:
1) As a foreign citizen NRN, one can keep the land/fixed assets he/she acquired (purchased or inherited) in Nepal prior to converting to foreign citizenship.
2) The areas of the land acquired (purchased or inherited) prior to converting foreign citizenship can be larger than what is listed in the subsection 1 and this can persist as is, after acquiring the foreign citizenship.

Can somebody clarify this and let me know whether my understanding is correct or not? Also, if you have the first hand experience of managing the inherited properties back in Nepal, can you please share how you have been doing so after converting yourself to a foreign citizen and if you have encountered any complication as such arising from not being a Nepali citizen in managing these? Thanks.
