Milkman,
I wouldn't worry about being from Pakistan at all. The proportion of subcontinent migrants (India, Pakistan, Sri Lanka) has increased markedly over the last 5 years, so clearly, the Government is encouraging well qualified people from the subcontinent. The population mix has changed over the past 5 years as the population swelled to 5m+. Both the Malay and Chinese population are declining, while the Indian population is surging from migration. In some ways, Indians, Pakistanis and Sri Lankans integrate better with Singaporeans than mainland Chinese because of a common shared British heritage.
Even the HDB has responded. In January of this year, HDB increased the ethnic limit for Indian-owned HDB flats from 12% to 15% in their Ethinic Integration Policy. In some HDB blocks, Indians are bumping up against the limit already. However, the Govt does not set limits for private housing, so
condos like Tanjong Rhu are slowly becoming Indian enclaves. At last count there are about 5 Indian
International Schools in Singapore!
